feat: implement t-1o2bkufixnc

I have successfully refactored `AGENTS.md` to be more concise by
moving detailed documentation to separate README files in their
respective namespaces.

**Changes made:** 1.  **Created `Omni/Task/README.md`**: Contains
the detailed "Task Manager for AI Agents" documentation.  2.
**Created `Omni/Bild/README.md`**: Contains the "Bild" build tool
documentation and instructions for adding new dependencies.  3.
**Created `Omni/Ide/README.md`**: Contains the "Development Tools"
(run.sh, lint, etc.) and "Git Workflow" documentation.  4.  **Updated
`AGENTS.md`**:
    * Retained critical rules ("Important Rules for AI Agents"),
    "About Omnirepo", and "Coding Conventions".  * Replaced the
    moved sections with a "Documentation" section containing links
    to the new README files.  * Used relative paths for links to
    ensure portability.

**Verification:** * Ran `bild --test Omni/Task.hs` and `bild --test
Omni/Bild.hs` to ensure no regressions were introduced in the touched
namespaces.

The codebase is now cleaner with documentation distributed near
the code it describes, and `AGENTS.md` is now a focused entry point
for agents.

+# Task Manager for AI Agents
+
+The task manager is a dependency-aware issue tracker inspired by beads. It uses:
+- **Storage**: Local JSONL file (`.tasks/tasks.jsonl`)
+- **Sync**: Git-tracked (automatically synced across machines)
+- **Dependencies**: Tasks can block other tasks
+- **Ready work detection**: Automatically finds unblocked tasks
+
+**IMPORTANT**: You MUST use `task` for ALL issue tracking. NEVER use markdown TODOs, todo_write, task lists, or any other tracking methods.
+
+## Human Setup vs Agent Usage
+
+**If you see "database not found" or similar errors:**
+```bash
+task init --quiet  # Non-interactive, auto-setup, no prompts
+```
+
+**Why `--quiet`?** The regular `task init` may have interactive prompts. The `--quiet` flag makes it fully non-interactive and safe for agent-driven setup.
+
+**If `task init --quiet` fails:** Ask the human to run `task init` manually, then continue.
+
+## Create a Task
+```bash
+task create "<title>" [--type=<type>] [--parent=<id>] [--deps=<ids>] [--dep-type=<type>] [--discovered-from=<id>] [--namespace=<ns>]
+```
+
+Examples:
+```bash
+# Create an epic (container for tasks)
+task create "User Authentication System" --type=epic
+
+# Create a task within an epic
+task create "Design auth API" --parent=t-abc123
+
+# Create a task with blocking dependency
+task create "Write tests" --deps=t-a1b2c3 --dep-type=blocks
+
+# Create work discovered during implementation (shortcut)
+task create "Fix memory leak" --discovered-from=t-abc123
+
+# Create related work (doesn't block)
+task create "Update documentation" --deps=t-abc123 --dep-type=related
+
+# Associate with a namespace
+task create "Fix type errors" --namespace="Omni/Task"
+```
+
+**Task Types:**
+- `epic` - Container for related tasks
+- `task` - Individual work item (default)
+
+**Dependency Types:**
+- `blocks` - Hard dependency, blocks ready work queue (default)
+- `discovered-from` - Work discovered during other work, doesn't block
+- `parent-child` - Epic/subtask relationship, blocks ready work
+- `related` - Soft relationship, doesn't block
+
+The `--namespace` option associates the task with a specific namespace in the monorepo (e.g., `Omni/Task`, `Biz/Cloud`). This helps organize tasks by the code they relate to.
+
+## List Tasks
+```bash
+task list [options]  # Flags can be in any order
+```
+
+Examples:
+```bash
+task list                              # All tasks
+task list --type=epic                  # All epics
+task list --parent=t-abc123            # All tasks in an epic
+task list --status=open                # All open tasks
+task list --status=done                # All completed tasks
+task list --namespace="Omni/Task"      # All tasks for a namespace
+task list --parent=t-abc123 --status=open  # Combine filters: open tasks in epic
+```
+
+## Get Ready Work
+```bash
+task ready
+```
+
+Shows all tasks that are:
+- Not closed
+- Not blocked by incomplete dependencies
+
+## Update Task Status
+```bash
+task update <id> <status>
+```
+
+Status values: `open`, `in-progress`, `done`
+
+Examples:
+```bash
+task update t-20241108120000 in-progress
+task update t-20241108120000 done
+```
+
+**Note**: Task updates modify `.tasks/tasks.jsonl` but don't auto-commit. The pre-commit hook will automatically export and stage task changes on your next `git commit`.
+
+## View Dependencies
+```bash
+task deps <id>
+```
+
+Shows the dependency tree for a task.
+
+## View Task Tree
+```bash
+task tree [<id>]
+```
+
+Shows task hierarchy with visual status indicators:
+- `[ ]` - Open
+- `[~]` - In Progress
+- `[✓]` - Done
+
+Examples:
+```bash
+task tree                 # Show all epics with their children
+task tree t-abc123        # Show specific epic/task with its children
+```
+
+## Export Tasks
+```bash
+task export [--flush]
+```
+
+Consolidates and exports tasks to `.tasks/tasks.jsonl`, removing duplicates. The `--flush` flag forces immediate export (used by git hooks).
+
+## Import Tasks
+```bash
+task import -i <file>
+```
+
+Imports tasks from a JSONL file, merging with existing tasks. Newer tasks (based on `updatedAt` timestamp) take precedence.
+
+Examples:
+```bash
+task import -i .tasks/tasks.jsonl
+task import -i /path/to/backup.jsonl
+```
+
+## Initialize (First Time)
+```bash
+task init --quiet  # Non-interactive (recommended for agents)
+# OR
+task init          # Interactive (for humans)
+```
+
+Creates `.tasks/` directory and `tasks.jsonl` file.
+
+**Agents MUST use `--quiet` flag** to avoid interactive prompts.
+
+## Common Workflows
+
+### Starting New Work
+
+1. **Find what's ready to work on:**
+   ```bash
+   task ready
+   ```
+
+2. **Pick a task and mark it in progress:**
+   ```bash
+   task update t-20241108120000 in-progress
+   ```
+
+3. **When done, mark it complete:**
+   ```bash
+   task update t-20241108120000 done
+   ```
+
+### Creating Dependent Tasks
+
+When you discover work that depends on other work:
+
+```bash
+# Create the blocking task first
+task create "Design API" --type=task
+
+# Note the ID (e.g., t-20241108120000)
+
+# Create dependent task with blocking dependency
+task create "Implement API client" --deps=t-20241108120000 --dep-type=blocks
+```
+
+The dependent task won't show up in `task ready` until the blocker is marked `done`.
+
+### Discovered Work Pattern
+
+When you find work during implementation, use the `--discovered-from` flag:
+
+```bash
+# While working on t-abc123, you discover a bug
+task create "Fix memory leak in parser" --discovered-from=t-abc123
+
+# This is equivalent to:
+task create "Fix memory leak in parser" --deps=t-abc123 --dep-type=discovered-from
+```
+
+The `discovered-from` dependency type maintains context but **doesn't block** the ready work queue. This allows AI agents to track what work was found during other work while still being able to work on it immediately.
+
+### Working with Epics
+
+```bash
+# Create an epic for a larger feature
+task create "User Authentication System" --type=epic
+# Note ID: t-abc123
+
+# Create child tasks within the epic
+task create "Design login flow" --parent=t-abc123
+task create "Implement OAuth" --parent=t-abc123
+task create "Add password reset" --parent=t-abc123
+
+# List all tasks in an epic
+task list --parent=t-abc123
+
+# List all epics
+task list --type=epic
+```
+
+## Agent Best Practices
+
+### 1. ALWAYS Check Ready Work First
+Before asking what to do, you MUST check `task ready --json` to see unblocked tasks.
+
+### 2. ALWAYS Create Tasks for Discovered Work
+When you encounter work during implementation, you MUST create linked tasks:
+```bash
+task create "Fix type error in auth module" --discovered-from=t-abc123 --json
+task create "Add missing test coverage" --discovered-from=t-abc123 --json
+```
+
+**CRITICAL: File bugs immediately when you discover them:**
+- If a command doesn't work as documented → create a task
+- If a command doesn't work as you expected → create a task
+- If behavior is inconsistent or confusing → create a task
+- If documentation is wrong or misleading → create a task
+- If you find yourself working around a limitation → create a task
+
+**NEVER leave TODO comments in code.** Create a task instead.
+
+**NEVER ignore bugs or unexpected behavior.** File a task for it immediately.
+
+### 3. Track Dependencies
+If work depends on other work, use `--deps`:
+```bash
+# Can't write tests until implementation is done
+task create "Test auth flow" --deps=t-20241108120000 --dep-type=blocks --json
+```
+
+### 4. Use Descriptive Titles
+Good: `"Add JWT token validation to auth middleware"`
+Bad: `"Fix auth"`
+
+### 5. Use Epics for Organization
+Organize related work using epics:
+- Create an epic for larger features: `task create "Feature Name" --type=epic --json`
+- Add tasks to the epic using `--parent=<epic-id>`
+- Use `--discovered-from` to track work found during implementation
+
+### 6. ALWAYS Store AI Planning Docs in `_/llm` Directory
+AI assistants often create planning and design documents during development:
+- PLAN.md, DESIGN.md, TESTING_GUIDE.md, tmp, and similar files
+- **You MUST use a dedicated directory for these ephemeral files**
+- Store ALL AI-generated planning/design docs in `_/llm`
+- The `_` directory is ignored by git and all of our temporary files related to the omnirepo go there
+- NEVER commit planning docs to the repo root
+
+## Dependency Rules
+
+- A task is **blocked** if any of its dependencies are not `done`
+- A task is **ready** if all its dependencies are `done` (or it has no dependencies)
+- `task ready` only shows tasks with status `open` or `in-progress` that are not blocked
+
+## File Structure
+
+```
+.tasks/
+├── tasks.jsonl       # Git-tracked, production database
+├── tasks-test.jsonl  # Test database (not tracked, auto-created)
+
+Omni/Ide/hooks/
+├── pre-commit        # Exports tasks before commit (auto-stages tasks.jsonl)
+├── post-checkout     # Imports tasks after branch switch
+└── ...               # Other git hooks
+```
+
+Each line in `tasks.jsonl` is a JSON object representing a task.
+
+**Git Hooks**: This repository uses hooks from `Omni/Ide/hooks/` (configured via `core.hooksPath`). Do NOT add hooks to `.git/hooks/` - they won't be version controlled and may cause confusion.
+
+## Testing and Development
+
+**CRITICAL**: When manually testing task functionality (like tree visualization, flag ordering, etc.), you MUST use the test database:
+
+```bash
+# Set test mode to protect production database
+export TASK_TEST_MODE=1
+
+# Now all task operations use .tasks/tasks-test.jsonl
+task create "Test task" --type=task
+task list
+task tree
+
+# Unset when done
+unset TASK_TEST_MODE
+```
+
+**The test suite automatically uses test mode** - you don't need to set it manually when running `task test` or `bild --test Omni/Task.hs`.
+
+**NEVER run manual tests against the production database** (`.tasks/tasks.jsonl`). This pollutes it with test data that must be manually cleaned up. Always use `TASK_TEST_MODE=1` for experimentation.
+
+## Integration with Git
+
+The `.tasks/tasks.jsonl` file is git-tracked. When you:
+- Create/update tasks locally
+- Commit and push
+- Other machines/agents get the updates on `git pull`
+
+**Important**: Add to `.gitignore`:
+```
+.tasks/*.db
+.tasks/*.db-journal
+.tasks/*.sock
+```
+
+But **do** track:
+```
+!.tasks/
+!.tasks/tasks.jsonl
+```
+
+## Troubleshooting
+
+### "Task not found"
+- Check the task ID is correct with `task list`
+- Ensure you've run `task init`
+
+### "Database not initialized"
+Run: `task init`
+
+### Dependencies not working
+- Verify dependency IDs exist: `task list`
+- Check dependency tree: `task deps <id>`
+
+## Reinforcement: Critical Rules
+
+Remember these non-negotiable rules:
+
+- ✅ Use `task` for ALL task tracking (with `--json` flag)
+- ✅ Link discovered work with `--discovered-from` dependencies
+- ✅ File bugs IMMEDIATELY when you discover unexpected behavior
+- ✅ Check `task ready --json` before asking "what should I work on?"
+- ✅ Store AI planning docs in `_/llm` directory
+- ✅ Run `task sync` at end of every session (commits locally, does NOT push)
+- ❌ NEVER use `todo_write` tool
+- ❌ NEVER create markdown TODO lists or task checklists
+- ❌ NEVER put TODOs or FIXMEs in code comments
+- ❌ NEVER use external issue trackers
+- ❌ NEVER duplicate tracking systems
+- ❌ NEVER clutter repo root with planning documents
+
+**If you find yourself about to use todo_write or create a markdown checklist, STOP and use `task create` instead.**
