Detects when all DB tasks are done/cancelled but the workstream status
is still 'active' — the pattern where a worker completes tasks via MCP
but forgets to call update_workstream_status(). Auto-fixable via --fix.
Also extends the C-04/C-05 fix path to handle C-13 (same PATCH logic).

Root cause: workplan files use "done" (task vocabulary) but the DB workstream
API only accepts "completed". The PATCH was silently failing with 422.
Fixes:
- Add FILE_TO_DB_WORKSTREAM_STATUS map and normalise_workstream_status()
- Normalise file status before C-04 comparison: done↔completed is no longer
spurious drift
- Normalise file status before PATCHing: always send DB-valid "completed"
- _api_patch now returns {"_error": ...} instead of None on failure, so the
fix loop reports FAILED entries rather than silently dropping them
- 9 new tests in TestNormaliseWorkstreamStatus (42 total)
