Trim low-value tests per review feedback

Removed ~29 tests that were adding noise rather than coverage:
- Registration boilerplate tests (16): redundant with registrations.test.ts
- Redundant role/type checks (3): consolidated into behavioral tests
- "Should not throw" tests (6): consolidated into single lifecycle test
- Constant identity tests (2): provided no safety net
- expect(true).toBe(true) test (1): replaced with actual assertion
- Weak capability test (1): removed, handler check already exists

Strengthened remaining tests:
- Resource templates test now verifies specific resource names
- File resources test now asserts registerResource was called

Test count: 124 → 95 (29 removed)
Coverage unchanged at ~71%
