test(pcc): add 10 real function tests

- capabilityScore partial/max score calculation (2 tests)
- LoopDetector record bool return value (1 test)
- learnFromActionResult cycle_count updates (2 tests)
- describeSelf format elements (1 test)
- diagnoseConsciousness valid state return (1 test)
- health timestamp verification (1 test)
- introspect model population (1 test)
- Fixed typo: consciousnessness → consciousness

Coverage: 76 → 85 tests (+9%)
