Step 8: Polish — lint, clock abstraction, e2e test.

- golangci-lint config with errcheck, govet, staticcheck, errorlint
- Fix all lint issues (unchecked error returns in cleanup paths, De Morgan)
- Inject jonboulle/clockwork into Garden for deterministic timestamps
- Add manifest.NewWithTime() for clock-aware initialization
- E2e lifecycle test: init → add → checkpoint → modify → status → restore → verify
- Update CLAUDE.md, PROJECT_PLAN.md, PROGRESS.md

Phase 1 (local) is now complete. All 9 CLI commands implemented and tested.
