Documentation Updater

Updates product documentation (.specweave/docs/) based on implementation progress.

When to Use

• Task specifies documentation updates in tasks.md
• Feature implementation is complete
• User says "update documentation" or "sync docs"
• After closing increment to ensure docs reflect reality

What It Does

1. Reads task requirements - Understands what was implemented from tasks.md
2. Updates living docs - Modifies .specweave/docs/ files with actual implementation
3. Status tracking - Changes [DRAFT] � [COMPLETE] on doc sections
4. Bidirectional links - Maintains links between docs and increments
5. Format adaptation - Matches existing doc structure (features/ or modules/)
