The previous sorting fix exposed a deeper bug: ResolvedMount always
mounted its staging directory as a single bind mount. When a config
profile mount targeted /workspace/x/y and contained a single file
z.json, the staging directory (containing only z.json) replaced the
ENTIRE /workspace/x/y directory, hiding all sibling files from git
repo mounts.
- Change apply_resolved_profile to mount each file individually:
- source: staging_dir/relative_path
- target: expanded_target/relative_path
- Sibling files from other mounts are preserved.
- Empty mounts produce no volume entries.
- Keep volume sorting (parent paths before child paths) which is
still necessary for directory mounts and ensures parent dirs exist
before file mounts inside them.
- Add 4 unit tests for file-level mount behavior.
