Add investigation type and duplicate detection (CF-166 Phase 1)
...
Enhancements:
1. Investigation Task Type
- Added 'investigation' to task type enum
- Migration 013: Updated PostgreSQL constraint
- Updated TypeScript schemas (task_add, task_list, task_update)
- Enables tracking research/debugging workflows
2. Duplicate Detection
- Enhanced task_add to check for similar tasks before creating
- Uses pgvector semantic search (>70% similarity threshold)
- Warns about potential duplicates with similarity scores
- Suggests linking command for related tasks
- Gracefully handles when embeddings unavailable
Example Output:
```
Created: CF-123
Title: Fix API rate limiting
Type: task
Priority: P2
Project: CF
⚠️ Similar tasks found:
- CF-120: Add rate limit monitoring (85% match, in_progress)
- CF-115: Implement API throttling (72% match, open)
Consider linking with: task link <from> <to> relates_to
```
Benefits:
- Prevents accidental duplicate tasks
- Surfaces related work automatically
- Reduces manual task linking
- Investigation type for research workflows
Files Changed:
- migrations/013_investigation_type.sql (new)
- src/tools/crud.ts (duplicate detection logic)
- src/tools/index.ts (investigation type in enums)
Remaining CF-166 Features (Phase 2):
- Session-aware task context
- Automatic linking within session
- Investigation workflow helper
- Task creation reminders
