iPhone app, round 6: one view picker, one-row composer, tall deck cards

A

Code views

A single view button sits in the Code header, left of the sessions button. It shows on the Code home, inside a session and in Shell.
It opens a small picker with Code, Terminal and Shell, with the current one ticked. Code takes you back from Shell to the regular view.
The Terminal and Shell pills are gone from the sessions sheet.

B

Composer

Everything sits on one icon row under the prompt, and nothing sits above it.
Left side: computer, folder, branch, worktree and permissions.
Right side: model, the context meter, and the Chat/Terminal toggle.
The toggle is one tap again. It shows the terminal icon in Chat and the chat bubble in Terminal.
The context meter now shows in the Terminal look too. Before a session has a figure it shows plan usage, or empty blocks.

C

Deck

Deck cards are tall portrait cards, 226 points wide, in a sideways row, as on the web.
This covers Bots home, bot Threads, Tasks, Groups, Projects, Artifacts, open chats and Code sessions.

D

Checked

The build passes. I checked the Bots home deck, the Code home, a Code session, the Terminal look and Shell in the simulator.
Pushed to #1942. The docs link check reports 0 problems.
