After the v5.3 driver-manager rebase rolled back the macro_replay
additions from Round 2, this commit re-adds them:
- src/editor/macro.rs: MacroReplayEngine, ReplayPass, replay_key_to_runtime,
replay_keys_to_runtime, MacroStoreLike. Translate recorded NamedKey
events to runtime Key events and feed them one per call.
- src/key/mod.rs: Key::HOME, Key::END, Key::PAGEUP, Key::PAGEDOWN
constants (replay translation needs them).
- src/editor/mod.rs: editor.macro_replay field + re-exports.
- src/editor/dispatch.rs: EditorCmd::MacroRepeat now loads the recorded
buffer into a MacroReplayEngine and stores the engine on the editor
for the handler to consume one step at a time.
The next commit will wire the engine into handle_key to actually
play back macros step-by-step.
Tests: 1486 passing (was 1486). No regression.
