fix(health): score module-level JS callbacks

[joptimus]

Summary

• collect module-level JS/TS lambda callbacks as scoreable complexity entries
• synthesize names for assigned lambdas and call-site callbacks
• skip outer test suite wrapper callbacks while still descending into their test/hook callbacks

Fixes #451.

Verification

• uv run pytest tests/unit/health/test_complexity_walker.py tests/unit/health/test_file_nloc.py -q
• uv run ruff check packages/core/src/repowise/core/analysis/health/complexity/walker.py tests/unit/health/test_complexity_walker.py

I also ran a read-only before/after validation harness against representative local projects without persisting health tables:

• Express-style API service: file NLOC stayed unchanged, route callbacks became scoreable entries, and new complexity/large-method signals appeared only where callback bodies had enough substance.
• TypeScript frontend app: file NLOC stayed unchanged; existing top health targets remained stable, with only callback/lambda entry coverage increasing.
• Desktop/app-style JavaScript project: file NLOC stayed unchanged; low-complexity event callbacks were collected but did not create new findings.

Validation also caught noisy suite-level test callbacks, so this PR skips describe/context/suite wrappers while still collecting nested it/hook callbacks.
