T34: prompts and commands carry OSC 133 marks: the tap reads every OSC body and hands 133's marks to the session, which keeps its last command's status; zsh, bash, fish and PowerShell mark what the shell leaves unmarked, and the user's prompt still sees the status

Ghostty is the bar for what the terminal does. ELYTerminal owns its engine on `alacritty_terminal`; Ely's `Terminal` is a gallery widget without mouse reporting, IME, kitty keys or style settings.

- Shell integration for zsh, bash, fish and PowerShell, injected at launch as Ghostty does: each prompt sends OSC 7 and a title. A shell without integration reports nothing, and the panels say so.
- Prompt marks, OSC 133: the shell integration marks where each prompt starts (A) and ends (B), where a command starts (C), and where it ends with its exit status (D); the terminal reads any program's OSC 133. Cmd-Up and Cmd-Down, and Cmd-Shift-Up and Cmd-Shift-Down, on macOS, Ctrl-Shift-Up and Ctrl-Shift-Down elsewhere, scroll to the prompt before or after the view's top, as in Ghostty.
- Program status, OSC 7501 revision 0.4: each terminal keeps the records programs report (state, id, kind, progress, app, title, msg), checked as the spec checks them; a new prompt drops working, blocked and idle records, a full reset drops them all; the terminal answers the support query with the states and kinds it takes.
