Builds on the in-composer prompt surface (D-78):
- Permission prompts (T-175): Allow / Allow-and-don't-ask-again / Deny.
"Don't ask again" appears only when the request carries a
permission_suggestion and echoes it back as updatedPermissions. An
optional note rides Deny as the message, or Allow as a follow-up user
message (the protocol has no allow-with-message).
- AskUserQuestion picker (T-176): a single question renders bare; 2-4
questions step one at a time (nav shows "N · Header", ✓ when answered)
then a review/confirm screen. Each question offers an "Other" free-text
choice and a per-choice note; multi-select joins labels. A "chat
instead" escape denies the prompt so the user can type freely. On
submit the answer is echoed into the log, since the card is ephemeral.
- Collapsed tool cards (T-177): multi-line tool_use / tool_result start
collapsed behind a one-line summary; one-line output renders inline.

Replaces the Claude pane's tmux-TUI + transcript-tail backend with
Claude Code's stream-json control protocol (D-77/D-78). A
StreamJsonSession owns the `claude` process: its event stream feeds the
existing ConversationController, and permission / AskUserQuestion
prompts arrive as can_use_tool control_requests. Those surface as a
ToolPrompt in the composer zone — the pane swaps the text input for an
Allow/Deny card or an option picker while a prompt is open, so
interaction stays out of the conversation stream and the prompt buttons
don't fight the message-card hover chrome. The decision is written back
as a control_response (allow echoes updatedInput; AskUserQuestion
answers go in updatedInput.answers). Unsupported control subtypes are
answered with an error so a turn never hangs.
Session continuity is --resume (existing transcript) vs --session-id
(new); /clear and /resume respawn the process. The transcript reader
still backs the sidebar/status/team surfaces. T-165, T-166.

The testable core of the stream-json pivot (D-77): StreamJsonSession drives
a claude process in stream-json mode — parsing its line-delimited events into
the existing ConversationItem / SessionStatus types (reusing
parseTranscriptChunk, since stream-json assistant/user events share the
transcript's message.content shapes), pulling permission-mode off the init
event, and sending user input as stream-json over stdin (with a local echo
so the user's own message renders immediately). The process is abstracted
behind StreamJsonProcess so it unit-tests without spawning; the real
ClaudeStreamJsonProcess wraps Process.start.
Not yet wired into the pane — the claude_pane integration (replace the
tmux/PTY spawn + TranscriptReader feed, route input through send) and live
verification are the next step.
T-165.
