* fix(backend): start agent immediately for passthrough quick-chat sessions
Passthrough profiles need a running PTY for the terminal to attach. When
launchPrepare is called with a passthrough profile, upgrade the request to
launchStart so the PTY exists by the time the frontend renders the terminal.
* fix(web): render passthrough terminal in quick chat for passthrough profiles
Quick chat used MessageList + ChatInputArea unconditionally, so passthrough
profiles showed an empty chat with no agent output (PTY never attached).
Render PassthroughTerminal when the active session is passthrough, mirroring
the task-page branch. Passthrough is detected via session.is_passthrough or,
before WS hydrates, via the agent profile's cli_passthrough flag — looked up
through a new agentProfileId stored on quickChat session entries (set by the
picker on selection and seeded by SSR for restored sessions).
* style(web): apply prettier formatting
* fix(web): address review feedback on quick-chat passthrough rendering
- Narrow `metadata.agent_profile_id` to string at runtime via a
`readAgentProfileId` helper instead of a blind type cast.
- Collapse `useIsQuickChatPassthrough` into a single `useShallow`
selector to avoid three separate store subscriptions.
* fix(backend): prevent launchPrepare ↔ launchStart recursion for passthrough
When passthrough quick-chat sessions hit a workflow step that blocks
auto-start, launchStart's downgrade to launchPrepare would have re-upgraded
back into launchStart and looped forever. Skip the passthrough upgrade when
AutoStart=true, since that flag uniquely identifies the downgrade path.
Adds tests for `isPassthroughProfile` and a regression test that runs the
launchStart→launchPrepare path under a deadline so future recursions surface.
* test(web): cover existing agentProfileId preservation on reopen
* style(web): apply prettier formatting
* test(backend): seed task with blocked workflow step in recursion regression
Without persisted task and step, shouldBlockAutoStart short-circuited to
false, the test bypassed the launchStart→launchPrepare downgrade entirely,
and removing the recursion guard would still pass. Seed the task with a
WorkflowStepID mapping to a step lacking auto_start_agent so the guard is
the only thing preventing the bounce. Verified by temporarily removing the
guard — the test now times out as expected.
* test(backend): cover ResolveAgentProfile error path in isPassthroughProfile
