feat(qa): add requirements traceability and TEA integration to QA checklist

Expand QA validation checklist with:
- Requirements Traceability section (all tracks):
  - Each acceptance criterion has at least one test
  - Each FR has at least one test scenario
  - Test descriptions reference their source FR/AC
- Enterprise Track TEA Module Integration section:
  - TEA TD (Test Design) completion check
  - TEA TR (Traceability) completion check
  - TEA NR (NFR Assessment) completion check
  - TEA quality gate decision (PASS/CONCERNS/FAIL)
  - RTM test column population from TEA output
  - Orphan test detection
- Enterprise Test Metrics section:
  - Coverage by requirement (TEA TR)
  - Coverage by risk P0-P3 (TEA TD)
  - NFR compliance (TEA NR)
  - Full traceability chain verification

Addresses GAP-QA02, C-QA1, C-QA2, C-QA3.

Part of ISO 29148 compliance initiative (Wave 2).

+## Enterprise Track: TEA Module Integration
+
+**When the TEA (Test Architecture Enterprise) module is installed, verify these additional items:**
+
+### TEA Workflow Completion
+
+- [ ] TEA TD (Test Design) has been run and test strategy document exists
+- [ ] TEA TR (Traceability) has been run and test-requirement traceability matrix exists
+- [ ] TEA NR (NFR Assessment) has been run if NFRs are present in the PRD
+- [ ] TEA gate decision has been obtained (PASS / CONCERNS / FAIL)
+
+### TEA Quality Gate
+
+- [ ] TEA quality gate result is PASS or CONCERNS (FAIL blocks progression)
+- [ ] If CONCERNS: issues documented and accepted by stakeholders
+- [ ] RTM test columns populated from TEA TR output
+- [ ] No orphan tests exist (every test traces to a requirement)
+
+### Enterprise Test Metrics (from TEA outputs)
+
+- [ ] Test coverage by requirement documented (from TEA TR)
+- [ ] Test coverage by risk level P0-P3 documented (from TEA TD)
+- [ ] NFR compliance status documented (from TEA NR)
+- [ ] Full traceability chain verified: Test → Story → FR → SyRS → StRS
