feat(cli): expand --uv-compile to all node management commands with conflict attribution (#2682)

* feat(cli): expand --uv-compile to all node management commands with conflict attribution

Add --uv-compile flag to reinstall, update, fix, restore-snapshot,
restore-dependencies, and install-deps commands. Each skips per-node
pip installs and runs batch uv pip compile after all operations.

Change CollectedDeps.sources type to dict[str, list[tuple[str, str]]]
to store (pack_path, pkg_spec) per requester. On resolution failure,
_run_unified_resolve() cross-references conflict packages with sources
using word-boundary regex and displays which node packs requested each
conflicting package.

Update EN/KO user docs and DESIGN/PRD developer docs to cover the
expanded commands and conflict attribution output. Strengthen unit
tests for sources tuple format and compile failure attribution.
Bump version to 4.1b3.

* 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
