When .laputa-cache.json was committed to git, cloned vaults carried
absolute paths from the original machine. The badge (from get_modified_files)
used fresh local paths while the list filtered entries by stale cached paths,
causing a mismatch.
Three-layer fix:
- Invalidate cache when vault_path differs from current machine (CACHE_VERSION bump)
- Exclude .laputa-cache.json via .git/info/exclude to prevent future commits
- Defense-in-depth: match entries by relative path suffix in NoteList
- Surface error message when modified files fetch fails
