Adds the actual right-alignment heuristic to toAsciiTable (was missing
from initial implementation). When any column header starts with a digit,
all columns are right-padded instead of left-padded. Matches the test
added in 53870d5 which exercises the right-alignment path with header
['Item', '7'].
All 6 ascii-table tests pass.
- useRegisterMenuCommands: registers file.open, file.save, file.closeTab,
tab.next, tab.prev, view.toggleSidebar, view.togglePreview in command store
- useBridgeNativeMenu: useMenuAction for 13 native-menu channels
(file-save, toggle-preview, load-template-menu, etc.)
- AppShell calls both on mount
- integration test mock extended to include ipc.menu.on
- 145/145 tests pass (was 105)
- bridge between main-process menu events and the command dispatcher
- optional transform: convert raw IPC payload to command args
- extends ipc.ts with ipc.menu.on() helper
- TDD: 5 unit tests covering subscription, payload transform, no-op, unmount
