Add enhanced dependency types to task manager

Implement four dependency types based on beads patterns: - Blocks:
Hard dependency, blocks ready work queue (default) - DiscoveredFrom:
Work discovered during implementation (doesn't block) - ParentChild:
Epic/task relationships (blocks ready work) - Related: Soft
relationships (doesn't block)

Key changes: - New Dependency data type with depId and depType fields
- New DependencyType enum with four relationship types - Updated CLI
with --dep-type and --discovered-from flags - Enhanced getReadyTasks
to respect only blocking dependency types - Added comprehensive tests
for all dependency behaviors - Updated AGENTS.md with usage examples
and patterns

The discovered-from pattern is especially important for AI agents to
maintain context of work found during implementation while keeping
it immediately available in the ready work queue.
