fix(muse code cat): FILE_NOT_TRACKED for untracked files; staged blobs readable from store

Same invariant as Phase 2 (muse cat), now applied to the symbol-level reader. _get_file_bytes in cat.py checks HEAD manifest + stage index before touching disk. Untracked files raise FILE_NOT_TRACKED regardless of disk presence. Staged-but-uncommitted files are readable via their object store blob.
