Add UnifiedDepResolver that batch-resolves all custom node pack
dependencies via uv pip compile, replacing per-node pip installs.
Core features:
- Collect, sanitize, and compile requirements from all node packs
- Input validation with regex-based sanitization and blacklist/override support
- Conflict detection with per-node-pack attribution output
- CollectedDeps.sources stores (pack_path, pkg_spec) tuples for attribution
- Startup integration via prestartup_script.py with fallback to legacy path
- --uv-compile flag on 8 CLI commands: uv-compile, install, reinstall,
update, fix, restore-snapshot, restore-dependencies, install-deps
Testing:
- 148 unit tests (mock-based) covering all resolver logic
- 12 E2E pytest tests using ltdrdata's dedicated conflict test packs
- E2E environment setup scripts (setup, start, stop)
- Supply-chain safety policy: only verified authors' packs in E2E
Documentation:
- PRD and DESIGN specs for the resolver
- EN/KO cm-cli user docs updated for all new commands
- Test documentation and environment setup guide
Bump version to 4.1b3.
