feat(cli): atm validate-calibration — offline color classification gate

Adds `atm validate-calibration LABEL_FILE` subcommand that runs the Detector
on a set of labeled PNG frames and reports per-sample PASS/FAIL with top-3
candidate colors and RGB-distance suggestions for failures. Exits 0 on 100%
PASS, 1 on any FAIL, 2 on missing/malformed label file.

- New module src/atm/validate.py with ValidationReport + SampleRecord
  dataclasses; reuses Detector.step(frame), does not reimplement color
  classification.
- main.py: new `validate-calibration` subparser and _cmd_validate_calibration
  handler wired into the dispatch map.
- samples/calibration_labels.json seeded with 3 entries from the 2026-04-17
  incident, plus a README describing the schema.
- tests/test_validate.py covers the 3 planned cases: PASS, FAIL w/ top-3
  + suggestion, missing file (graceful error, no traceback).

+## Skill routing
+
+When the user's request matches an available skill, ALWAYS invoke it using the Skill
+tool as your FIRST action. Do NOT answer directly, do NOT use other tools first.
+The skill has specialized workflows that produce better results than ad-hoc answers.
+
+Key routing rules:
+- Product ideas, "is this worth building", brainstorming → invoke office-hours
+- Bugs, errors, "why is this broken", 500 errors → invoke investigate
+- Ship, deploy, push, create PR → invoke ship
+- QA, test the site, find bugs → invoke qa
+- Code review, check my diff → invoke review
+- Update docs after shipping → invoke document-release
+- Weekly retro → invoke retro
+- Design system, brand → invoke design-consultation
+- Visual audit, design polish → invoke design-review
+- Architecture review → invoke plan-eng-review
+- Save progress, checkpoint, resume → invoke checkpoint
+- Code quality, health check → invoke health

+## P2-yaxis-recalib-detect — Y-axis recalibration detection
+
+Price overlay (from Telegram commands feature) uses `y_axis` linear interpolation to show current price on screenshots. When the user rescales the chart y-axis (common after overnight price gaps), the calibration becomes stale and prices shown are incorrect. Canary check detects layout drift but NOT y-axis range changes.
+
+- Possible approaches: OCR on y-axis labels (fragile), track price range consistency across sessions, or simple "calibration age" warning after N hours.
+- Start after price overlay is live and the false-price frequency is known.
+- Depends on: Telegram commands + price overlay feature being shipped.
+
 ## Quality debt
 
-- [ ] **Integration test for run_live loop**: currently mocked at module level. Add a short-duration in-memory loop test that threads real detector/state_machine/audit together (no network).
+- [x] **Integration test for run_live loop**: lifecycle async test added in `tests/test_main.py` (IDLE→ARMED→PRIMED auto-poll→FIRE auto-stop).
 - [ ] **Coverage report**: run `pytest --cov=atm --cov-report=term-missing`, aim for ≥ 85% per module.
 - [ ] **Typing strictness**: run `pyright src/` with strict mode, fix reported issues.
 - [ ] **Perf baseline**: profile one detection cycle on a representative frame; ensure < 100ms so 5s loop has ample headroom.
