Watch: snooze finished threads, name the files a file approval would edit, Settle on finished notifications, an instant launch from the saved feed, plain Loading states, and no more cancelled errors

+## Snooze
+
+Snooze hides a finished thread from Recent until a time you pick, and the gateway brings it back on
+its own. The Recent swipe has a violet Snooze beside Settle, and the thread screen has a Snooze
+button beside Settle. Both open the Snooze until picker with four choices in the watch's time zone:
+In 1 hour, This evening at 6 PM, Tomorrow at 9 AM, and Next week, which is next Monday at 9 AM. From
+5 PM on, the picker leaves out This evening. Once `POST /v1/threads/:hostId/:threadId/snooze` succeeds, the thread leaves
+Recent and the feed refreshes. When any thread is snoozed, a dim violet row under Recent counts them
+and opens the Snoozed list (`GET /v1/snoozed`), where each card says when it wakes and swipes left
+to Unsnooze.
+
+## File approvals
+
+A file-change approval names its files in place of the raw prompt, on the feed card, the thread
+screen and the notification: "Wants to edit" and the file name, or "Wants to edit 3 files" with a
+row for each. The line counts show on the right only when the gateway has them, and the thread
+screen adds the first changed lines in red and green. Claude sends no diff before approval, so in
+practice the name shows alone. Without files, the prompt shows as before.
+
+## Loading and launch
+
+Every screen that loads data shows a plain "Loading" until its first answer. Once a screen has
+content, a refresh keeps it on screen, and a failed refresh only adds a small dim line under it.
+The error and Try again replace the placeholder only when there is nothing to show. When a screen
+goes away mid-request, the cancelled request shows no error.
+
+On every refresh the app saves the last good feed as JSON in its caches folder, and it saves each
+thread's detail when the thread loads. Launch shows the saved feed at once, with a dim "Updating" by the
+count until the first refresh answers, and a thread opens on its saved detail while it loads.
+Unpairing clears both. Demo mode never touches them.
