tlc: phase 20 wire-up — F9 menubar fully integrated
Connect the standalone editor::menubar module into the editor's
main loop:
editor/mod.rs:
- Add menubar: Option<EditorMenuBar> field on Editor struct
- Init menubar: None in both Editor::open and Editor::new_empty
- Add dispatch_editor_cmd(cmd) -> EditorResult, mapping
EditorCmd to existing editor methods:
Undo, Redo, Cut, Copy, Paste, GotoTop, GotoBottom,
BookmarkToggle (opens BookmarkSet prompt),
BookmarkClearAll, GotoLine (opens GotoLine prompt).
Not yet wired (New, Open, Save, SaveAs, Quit, Find,
FindNext, FindPrev, Replace, BookmarkNext/Prev, Settings)
surface 'F9: ... (not yet wired)' message.
editor/handlers.rs:
- At top of handle_key, route through menubar when Some
(Esc/F9 → Close, Enter → Dispatch, arrows/hotkeys → Running).
- F9 keybind opens menubar.
editor/render.rs:
- When menubar is Some, split area into [Length(1) menubar,
Min(1) editor]. Pass lower area as editor_area to existing
layout, replacing two 'area' references with 'editor_area'.
Tests: 1132 passed (was 1129, +3 handler tests covering open,
Esc-close, dispatch-undo integration end-to-end).
Ref: MC src/editor/editmenu.c (six menus), editor handle_key
routing precedence for menubar overlay (matches filemanager).
