Most terminals and editors have shell-style history recall; the desktop
composer was a plain textarea. Wire ⌥↑ / ⌥↓ to step through the user's
last 200 sent prompts (most-recent first), persisted in localStorage at
reasonix.composer.history.
Behavior matches readline:
- First ⌥↑ stashes the in-progress draft and shows the most recent
prompt; subsequent presses walk further back.
- ⌥↓ walks forward; stepping past the newest entry restores the
stashed draft so the user's typing isn't lost.
- The modifier is Alt (Alt on Linux/Windows, Option on macOS) — plain
ArrowUp/Down still drive the slash / @-file / arg menus, so the two
paths don't fight.
- isComposing guards IME confirmation (pinyin, kana) so an in-progress
composition is never swallowed by a recall.
- submit() resets the cursor and the draft, so the next recall starts
fresh.
- Sending pushes the typed text (post-trim, attachments excluded) to
the head of the list, deduped.
New file lib/composerHistory.ts (pushHistory / snapshot / clearHistory,
capped at 200 entries, defensively copies on read so a caller can't
mutate the cache).
