fix(ui): stabilize shell rolling output transitions

- Remove anim.stop() from useRowWipe cleanup — stopping mid-animation
  leaves WAAPI fill-forward that overrides cleared inline styles. Let
  animations run to completion; cancelAnimationFrame prevents starts.
- Add generation counter to useCollapsible to guard against stale
  microtask and promise callbacks on rapid open/close toggling.
- Use .then(ok, err) instead of .catch().then() to prevent callbacks
  firing after animation cancellation.
- Remove redundant fade constant in ShellExpanded.
- Clean up unused imports in context-tool-results.tsx.

+/**
+ * Composer Island migration tracker
+ *
+ * Goal
+ * - Replace the split composer stack (PromptInput + question/permission/todo docks)
+ *   with a single morphing ComposerIsland + app runtime adapter.
+ *
+ * Current status
+ * - [x] Storybook prototype with morphing surfaces exists (`packages/ui/src/components/composer-island.tsx`).
+ * - [ ] App still renders the existing production stack (`session-composer-region` + `prompt-input`).
+ *
+ * Feature parity checklist
+ * - [ ] Submit pipeline parity (session/worktree/create, optimistic user message, abort, restore on error).
+ * - [x] Runtime adapter API boundary in island (`runtime.submit`, `runtime.abort`, lookup, permission/question handlers).
+ * - [x] Shell mode wiring parity (single mode source for tray + editor).
+ * - [x] Cursor scroll-into-view behavior in island editor.
+ * - [x] Attachment parity in island UI: image + PDF support and file picker wiring.
+ * - [x] Drag/drop parity in island UI: attachment drop + `file:` text drop into @mention.
+ * - [x] Keyboard parity in island UI: mod+u, ctrl+g, ctrl+n/ctrl+p, popover navigation.
+ * - [x] Auto-accept + stop/send state parity in island UI.
+ * - [x] Async @mention/slash sourcing parity in island via runtime search hooks.
+ * - [ ] Context item parity (comment chips/open behavior is in progress; app comment wiring still pending).
+ * - [ ] Question flow parity (island submit/reject hooks + sending locks done; app SDK/cache wiring pending).
+ * - [ ] Permission flow parity (island responding lock done; app tool-description wiring pending).
+ * - [x] Todo parity in island UI (in-progress pulse + auto-scroll active item).
