Implements all 5 critical parity items from the comprehensive MC
assessment. Reference: MC source at local/recipes/tui/mc/source/.
A1 — Editor line number gutter:
Split editor inner area into gutter_area + body_area; gutter
renders right-aligned line numbers (or relative offsets when
relative_lines mode is on); bookmark rows show current-line
style; ~ shown for lines past end-of-file.
A2 — Viewer cursor line highlight:
cursor_line_bg derived from body_bg + RGB(12,12,12); applied
before search-match overlay so matches win on the cursor line.
A3 — Hide terminal cursor in file manager mode:
App::run() hides the cursor after Tui::new(); render() shows
the cursor only when editor/viewer/cmdline/dialog/menubar
is active.
A6 — Shift-F5/F6 same-directory rename:
New Cmd::CopySameDir and Cmd::MoveSameDir variants, bound to
Shift-F5 / Shift-F6. Reuse CopyDialog/MoveDialog with a new
same_dir flag and new_rename() constructor; result() resolves
the typed name against the source's parent directory.
A7 — SUID/SGID/sticky bits in chmod dialog:
4-row PermCell grid (user, group, other, special); class_shift
= 0o4000, bit = 1. Display as 0oXXXX. Overwrite dialog shows
all 12 cells. 6 new unit tests cover all special-bit combinations.
Other fixes in the same commit:
- 4 editor render tests shifted x-coordinates by gutter_chars
to account for the new gutter column.
- 1 viewer text test moves cursor to line 1 so cursor-line
highlight doesn't overlap the search-match assertion.
Tests: 1230 passed (was 1219 before A7; +11 new tests across A7
and A6). All Sprint 1 items compile clean.
