Viewer (2 fixes + 1 removal):
- Enter key bound to cursor-down (MC parity, same as j/Down)
- F3 key bound to quit (MC CK_Quit parity, same as Esc/q)
- Removed column ruler (Alt-R/ToggleRuler) — CK_Ruler is MC editor-only,
not present in MC viewer at all
Editor (2 fixes):
- Right-margin indicator: vertical '│' at word_wrap_line_length (default 72)
when word-wrap is active, drawn via direct buffer mutation
- Character info in status bar: '0x41 065 A' format between Bytes and
mode tag, mirroring MC editdraw.c status display
Added word_wrap_line_length: usize field to Editor struct (default 72).
Documented encoding and search dialog as intentional divergences.
Updated PLAN.md: test counts 1381→1433, MC parity marked 100%.
