feat(P02): behavioral verification now executes tests and reports real pass/fail

---ci---
project: ci
phase: 2
milestone: v0.8
status: complete
decisions:
  - id: D-027
    decision: L2 behavioral verification runs npm test via jest --json
    rationale: Static-only checks gave false confidence; real test execution shows actual status
    confidence: 0.92
  - id: D-028
    decision: Add must-have stub test generation to behavioral verification
    rationale: Plans specify must_haves; auto-generating stubs ensures test coverage
    confidence: 0.85
requirements:
  covered: [BEH-01, BEH-02, BEH-03, BEH-04, BEH-05]
---/ci---

BEH-05: Behavioral verification passed=false when any check has status=fail
(added checkTestExecution that returns fail on test failures).

BEH-01: checkTestFramework now actually runs tests via jest --json
--outputFile and parses the JSON results, reporting pass/fail counts.

BEH-02: checkTestFiles now reports per-suite pass/fail from jest output,
not just file existence.

BEH-03: New checkTestExecution() runs npm test, parses Jest JSON output,
collects coverage metrics from coverage-summary.json, and returns
fail/pass based on test execution results.

BEH-04: New generateMustHaveStubTests() method produces .test.ts
skeletons from must-have descriptions.
