fix: include non-.md files in vault cache incremental updates

The cache's git helper functions (collect_md_paths_from_diff,
collect_md_paths_from_porcelain, git_uncommitted_files) filtered for
.md files only. This meant .yml view files created by save_view were
never detected by the incremental cache update, so they didn't appear
in vault entries until a full rescan.

Renamed the helpers to collect_paths_from_diff/collect_paths_from_porcelain
and replaced the .md filter with a hidden-segment filter, matching the
behavior of scan_all_files which already includes all non-hidden files.
