The core-side machinery the menu and clipboard ride on, plus the Lua
resolver. Still no dispatch wiring (that needs the protocol/frontend
commit), so this builds but nothing is reachable yet.
- Clipboard (Q#CM6): an in-core slot + `copy`/`cut`/`paste`/`select-all`
on `EditorCore`, plus a one-shot `pending_clipboard` the dispatcher
will drain. `region_bytes` / `word_at_cursor` (the latter feeds the
`symbol` context).
- Menu core (Q#CM1): `SharedMenu` field + `menu_open/close/step/
set_active_row/active_command/hit` + `ensure_menu_overlay`.
- `pmacs.menu` install (item/list/remove/clear/_raw) and `ed.*` bindings
(clipboard_copy/cut/paste, select_all, word_at_cursor); the `install`
signature gains the menu registry, threaded through `lua.rs`.
- `builtin/menus/default.lua`: `pmacs.menu.build` resolves visible items
(predicate or context tag), groups/sorts, and emits rows (Q#CM3). The
default items reference commands by name (resolved at invoke).
