Module manifest 

Manifest tracking indexed files with a Merkle tree for fast change detection.

The manifest stores per-file metadata (mtime, size, content hash, chunk count) and per-directory metadata (mtime, hash). Directory hashes are computed bottom-up from children’s content hashes, enabling top-down pruning during diffs.

File metadata for change detection and cache lookup.

Persistent manifest tracking all indexed files and their state.
