feat(resource): implement ResourceHandler sandbox and checkpoint methods
Extend the ResourceHandler protocol with four sandbox/lifecycle methods:
create_sandbox (idempotent), create_checkpoint, rollback_to, project_access.
Fixes from self-review:
- Instance-level checkpoint dict instead of ClassVar (no shared state)
- Git rollback uses 'git reset --hard' + 'git clean -fd' (not just checkout)
- FsDirectory rollback skips .git to preserve git metadata
- project_access separates ImportError (local mode) from ValueError (reject)
- Added discard_checkpoints() cleanup method
- Git rollback test verifies file content restored
