refactor(cli): extract _finalize_resolve helper, add CNR nightly fallback and pydantic guard

- Extract `_finalize_resolve()` to eliminate 7x duplicated uv-compile
  error handling blocks in cm_cli (~-85 lines)
- Move conflict attribution regex to `attribute_conflicts()` in
  unified_dep_resolver.py for direct testability
- Update 4 attribution tests to call production function instead of
  re-implementing regex
- Add CNR nightly fallback: when node is absent from nightly manifest,
  fall back to cnr_map repository URL (glob + legacy)
- Add pydantic Union guard: use getattr for is_unknown in uninstall
  and disable handlers to prevent Union type mismatch
- Add E2E test suites for endpoint install/uninstall and uv-compile
  CLI commands (conflict + success cases)
- Add nightly CNR fallback regression tests
