aiongg 9f89fe8f6d Add craft-menu: one menu definition, native on macOS and an egui bar on Windows, Linux and web (#66)
* Add craft-menu: Mac menu-bar layout and native-menu driver

A platform-free menu model (built directly or from flat rows), the macOS
layout (app menu, Window, Help, system-key clash resolution, translatable
labels), and NativeMenu, which feeds a backend's key equivalents to egui as
key presses, runs Minimize and craft-quit's Quit, and re-syncs only when the
app's state changes. Generalised from PhotoCraft's native_menu.rs.

* craft-menu: macOS menu bar through muda

* craft-menu: clipboard keys, layout-assigned shortcuts, Hide Others and atomic rebuilds

* craft-menu: menu key equivalents run while a text field has the keys

* craft-menu: commands as CommandRef, item kinds, craft-keymap chords

Items and rows run a craft_keymap::CommandRef and take a craft_keymap::Chord
shortcut; crates/menu/src/chord.rs is gone. Native ids are the command's key,
made unique with #2, #3 when a command is shown twice. Item.checked becomes
ItemKind { Plain, Check, Radio } (radio shows as a check item on macOS).
The built-in items' commands are Builtin::{Hide, HideOthers, Minimize, Quit}.
MenuRole gains Edit, View and Other; tag_submenu finds its menu by role.
While text editing, the keys left to the field are the clipboard keys and
craft_keymap::text_editing_chords. Adds the Platforms, Document and Gate types
(data only) and MenuBar::documents.

* craft-menu: Gate::allows, the one rule for what may run from the menus

* craft-menu: Windows, Linux and web layouts, documents in Window, keymap adapter

layout(bar, Target, options) dispatches to mac_layout, desktop_layout or
web_layout. Every layout drops what the target's Platforms leave out and lists
MenuBar::documents as radio items last in the Window menu (ItemRole::Document
is gone). Windows and Linux put About in Help, Settings in Edit as
Preferences and Quit in File (Exit on Windows); the web layout has no Quit and
takes the browser's own shortcuts off the items, reporting clashes. tidy drops
empty submenus.

apply_keymap sets shortcuts and toggle check items from a craft-keymap Keymap;
apply_state sets enabled and checked per frame.

* craft-menu: the egui-drawn menu bar for Windows, Linux and the web

* craft-menu: gate, command hook and one muda handler for the native menu

- NativeMenu::set_gate: app items greyed in place while modal or recording a
  shortcut; take_clicks drops clicks the gate forbids when they are taken.
  While recording, key equivalents reach egui as plain key presses.
- NativeMenu::on_command: a hook called from the menu event handler for each
  allowed app click; take_clicks still returns every command.
- Dispatch, shared between the driver and the backend's handler
  (Backend::attach replaces Backend::set_text_editing).
- Only Cmd or Ctrl chords become key equivalents; other shortcuts are not
  shown natively (building an attributed title needs unsafe objc2 calls).
- mac: one muda event handler per process, routed to the latest install;
  mac::install_app_menu ports craft-quit's minimal app menu onto it.
- craft_quit::install_app_menu is deprecated in favor of
  craft_menu::mac::install_app_menu.

* craft-menu: the bar takes Target, README section and NOTICE credit

* craft-menu: bar tests beside the layout and native ones; only a click outside closes the menus

* craft-menu: clippy (complex types, Copy clones, elided lifetimes)

* craft-menu: keyboard access to the egui bar

A tap on Alt alone or F10 focuses the bar, Alt+letter opens a menu and
a letter in an open menu runs or opens the row with that mnemonic, as
in a Windows menu bar. Mnemonics are assigned per level from the shown
labels, underlined only while the keyboard drives the bar, and a label
without an ASCII letter shows its English letter after it ("文件(F)")
through the optional english hook. Preferred letters come from
MenuBarUi::mnemonics. A Mac target has none, and a dialog or the
shortcut recorder keeps the keys. Ported from PhotoCraft's menu_keys.rs
and menu_keys_tests.rs.

* craft-menu: one installer or the other; sort mnemonics before checking uniqueness

* craft-menu: egui 0.37

* craft-menu: text fields keep their Edit items; web names by the browser's system; sync per frame; stable check kinds; handled hook clicks

* craft-menu: sync reports a clash change on an unchanged bar
