The sidebar notice offers mod+z to undo a settle, snooze, archive or unpin, but the shortcut skipped focused text fields, and the composer is almost always focused. Settling the open thread even moves focus into the next thread's composer. A new notice now claims mod+z from text fields until the user presses another key or edits text. The shortcut listens in the capture phase so the editor's own undo cannot consume the key first, and it moves next to the sidebar so it works on every route that shows the notice. Fixes pingdotgg#16159

Review comments at @apps/web/src/components/AppSidebarLayout.tsx:
- Around line 239-243: Update the keydown handler around undoLatestThreadAction
so repeated keydowns do not invoke thread undo again but are prevented and
stopped when the undo notice still claims the mod+z shortcut. Keep repeats
uncanceled when no claim is active, and preserve the palette checks.
Review comments at @docs/user/keybindings.md:
- Around line 130-131: Update the shortcut-claim guidance in
docs/user/keybindings.md at lines 130-131 to say that another keypress or a text
edit returns mod+z to the focused field. Apply the same release condition to the
composer guidance in docs/user/thread-sidebar.md at line 54.

Fixes #16159
After you settle, snooze, archive or unpin a thread, the sidebar notice says "⌘Z to undo", but ⌘Z did nothing in practice. The
thread.undobinding skipped focused text fields, and the composer almost always has focus: ChatView focuses it on every thread change, and settling the open thread moves you to the next one. So ⌘Z went to the composer's own text undo. The notice also shows on/usageand project pages, where no ⌘Z handler was mounted at all.Fix
A new notice claims ⌘Z, even inside a text field, until you press any other key or edit text. Input events also cover pasting from a menu, dictation and drops. After that, ⌘Z is the field's own undo again. The claim only applies while the notice is visible: with the sidebar collapsed, text fields keep their own undo, as on
main. Terminals keep their shortcut. Holding ⌘Z undoes once.The handler moves from the
_chatroute to the root sidebar layout, next to the back/forward shortcut, so it works on every route that shows the notice. Settings hides the notice, so the handler isn't mounted there. It listens in the capture phase, so the editor's undo keymap can't consume the key first. The storedthread.undobinding is unchanged: remaps keep working and no keybinding migration is needed.This qualifies as a small fix for an obvious bug: the notice advertises a shortcut that doesn't work in the default state. #14339 targets the same bug by tracking the composer editor's undo history and resetting it across thread switches, sends and queued edits. It only yields ⌘Z when the composer is empty, and it also changes notice expiry on hover. This PR changes 3 source files and leaves the editor alone. It also works when the next thread has a saved draft.
Verification
vp test run src/hooks/showThreadUndoNotice.test.ts src/hooks/useThreadActions.undo.test.ts src/keybindings.test.tsinapps/web: 3 files, 151 tests passed. Two new tests cover the claim rules. A notice claims ⌘Z, typing releases it, and a new notice claims it again. The claim also ends when nothing is left to undo or the notice expires.Not checked yet: the interaction in a real client. The T3 Browser panel in my desktop app couldn't reach the dev server on my Linux box, so there's no before/after recording yet. I'll add one here. Also not exercised: IME, Windows and Linux keyboards, and the desktop Edit menu accelerator.
