fix: replace is-hotkey with @portabletext/keyboard-shortcuts

[christianhg]

What changed

Replaces the is-hotkey dependency with @portabletext/keyboard-shortcuts (already in the monorepo).

Why

is-hotkey doesn't ship ESM.

How

Rewrote packages/editor/src/slate-dom/utils/hotkeys.ts to use createKeyboardShortcut(). Each hotkey is defined with explicit KeyboardEventDefinition objects instead of is-hotkey string syntax.

All modifier constraints are explicit. is-hotkey defaults unmentioned modifiers to false (must be off), while createKeyboardShortcut treats undefined as don't-care. Every definition specifies all four modifiers to preserve the original behavior. The shift? optional modifier maps to omitting shift (undefined = don't care).

The original code checked generic hotkeys first, then platform-specific ones (both could match on Apple). createKeyboardShortcut selects apple OR default based on platform, so generic definitions are merged into the apple arrays where both should match.

Removed is-hotkey and @types/is-hotkey from package.json.

What to review

• Hotkey mappings, especially:
  • deleteBackward: generic Backspace (shift optional) + apple ctrl+Backspace/ctrl+h
  • moveWordBackward/moveWordForward: generic ctrl+arrow + apple alt+arrow
  • redo: windows ctrl+y/ctrl+shift+z, apple cmd+shift+z
  • compose: plain key matching with explicit modifier rejection
