Relay 0.26.0

TL;DR: The thread's details move into one Running card, permission prompts sit on the composer, and the phone opens long threads much faster.

• The Running card beside the thread now holds what used to crowd the titlebar: the computer and its load, Hand off, the thread's folder and branch, and its changes. It stays open beside the thread, folds into a stripe in the gutter, and doesn't show on a new thread.
• Permission prompts show as a tab on the composer: Decline, Always or Allow, and a click opens the details.
• On the phone, finished turns arrive folded and load their steps when you open them, so long threads open several times faster. An opened fold stays where it is instead of jumping to the end, and its steps stay in the offline copy.
• Move a started thread to any branch you pick, and a deep review runs where the picked branch is checked out. You can switch a started thread's branch from the phone too.
• The browser panel opens several pages, and ⌘R / Ctrl+R reloads the page in front.
• A new-shell key opens another terminal beside the one you're typing in, and ▶ sends to the shell you used last.
• ⌘K / Ctrl+K opens thread search (⌘P / Ctrl+P still works). Opening a pull request by URL moved to ⌘⌥K / Ctrl+Alt+K.
• Schedules are listed in the sidebar, and the Threads button on the activity bar carries the sidebar's dot. The activity bar folds away with the sidebar.
• Servers Claude left running no longer make a thread look like it's waiting.
• Claude's context ring measures against the point where it auto-compacts.
• A new thread keeps the account you picked until its first message.
• Usage meters no longer flip colour a point either side of their pace mark.
• Gifs play in phone threads.
• Windows and Linux get their own CLI install hints, and name the Recycle Bin and Alt+click instead of the macOS words.
• A waiting thread's dot pulses three times, then holds, instead of pulsing forever.
