feat(token-tracking): record AI token consumption per task (CUST-WP-0029)
Introduces end-to-end token consumption tracking so agent work is
visible as a cost/effort metric alongside tasks and workplans.
- Migration o2j3k4l5m6n7: token_events table with FK indexes on
task_id, workstream_id, repo_id, created_at
- ORM model, Pydantic schemas (TokenEventCreate, TokenEventRead with
computed tokens_total, TokenSummary)
- Router: POST /token-events/, GET /token-events/ (7 filters),
GET /token-events/summary/ (task|workstream|repo|commit|release scope)
- MCP tools: record_token_event, get_token_summary (formatted table)
- update_task_status enriched with optional tokens_in/tokens_out
passthrough — one call creates status update + token event
- Dashboard token-cost.md page: by-repo bar, by-workplan table,
by-model bar, top-10 tasks by tokens
- ralph-workplan skill updated with token reporting guidance and
per-task heuristics for estimating counts
- Tests: test_token_events.py + test_token_passthrough.py (182 pass)
