Phase A of MC-PARITY-AUDIT.md. Brings TLC's panel display from ~50% to
~100% MC-compatibility per MC 4.8.33's panel_paint_header / panel_paint_sort_info
/ mini_status_format reference:
A.1. F-key bar labels: Move→RenMov, MkDir→Mkdir, Del→Delete, Menu→PullDn
A.2. Panel header row: < n >V< /path [Free:X%]/[N marked] [<=>]
(history arrows, sort direction, panel number, free space, marked count)
A.3. Sort direction arrows: 'desc' text → ▼/▲ Unicode
A.4. Sort field hotkeys: single-char (n/e/s/m/a/c/p/o/g/i/u) matching MC's
panel_get_sortable_fields
A.5. Long mode row: full ls -l columns (perm nlinks owner:group size mtime name)
A.6. Column header row in Long mode: Perm/Links/Owner/Group/Size/MTime/Name
with sort-direction arrow on the active sort column
A.7. Mini-status: UP--DIR for '..', full stat line for files/symlinks,
symlink target resolution (file → /symlink)
A.8. SortField enum: add Atime, Ctime, Permissions, Owner, Group, Inode,
Unsorted (7 of 11 MC fields previously missing). New sort_in_place
arms for each. New config-string keys: 'atime', 'ctime', 'perm',
'owner', 'group', 'inode', 'unsorted'.
fs/stat.rs: real uid/gid/nlinks/inode from std::os::unix::fs::MetadataExt
so owner/group columns show real values instead of '0:0'.
Tests: 1474 passing (was 1433). Zero new warnings. Cross-stage_grep confirms
no regression.
