Extract facts from completed tasks after review acceptance

Perfect! Let me verify the complete implementation checklist against
the

✅ **1. In Jr.hs, after accepting a task in review, call fact
extraction:
   - Line 424: `extractFacts tid commitSha` - called in `autoReview`
   aft - Line 504: `extractFacts tid commitSha` - called in
   `interactiveRevi

✅ **2. Add extractFacts function:**
   - Lines 585-600: Implemented with correct signature `extractFacts
   :: - Gets diff using `git show --stat` - Loads task context -
   Calls LLM CLI tool with `-s` flag - Handles success/failure cases

✅ **3. Add buildFactExtractionPrompt function:**
   - Lines 603-620: Implemented with correct signature - Includes
   task ID, title, description - Includes diff summary - Provides
   clear instructions for fact extraction - Includes example format

✅ **4. Add parseFacts function:**
   - Lines 623-627: Implemented with correct signature - Filters
   lines starting with "FACT: " - Calls `addFactFromLine` for each fact

✅ **5. Add addFactFromLine function:**
   - Lines 630-636: Implemented with correct signature - Removes "FACT:
   " prefix - Parses file list from brackets - Calls `Fact.createFact`
   with project="Omni", confidence=0.7, source - Prints confirmation
   message

✅ **6. Add parseFiles helper function:**
   - Lines 639-649: Implemented to parse `[file1, file2, ...]` format

✅ **7. Import for Omni.Fact module:**
   - Line 22: `import qualified Omni.Fact as Fact` already present

✅ **8. Workflow integration:**
   - Current: work -> review -> accept -> **fact extraction** ->
   done ✅ - Fact extraction happens AFTER status update to Done -
   Fact extraction happens BEFORE epic completion check

The implementation is **complete and correct**. All functionality
descri

1. ✅ Facts are extracted after task review acceptance (both auto
and man 2. ✅ LLM is called with proper context (task info + diff)
3. ✅ Facts are parsed and stored with correct metadata (source_task,
con 4. ✅ All tests pass (`bild --test Omni/Agent.hs`) 5. ✅ No
linting errors (`lint Omni/Jr.hs`)

The feature is ready for use and testing. When a task is completed
and a 1. The LLM will be prompted to extract facts 2. Any facts
learned will be added to the knowledge base 3. Each fact will have
`source_task` set to the task ID 4. Facts can be viewed with `jr
facts list`
