The setup bot's two tools now render as native cards in the desktop chat.
setup_choose goes through the clarify card path instead of a second card:
the renderer answers the setup_choose server request, parks it in the
clarify store (so the needs-input dot, the notification, the composer's
type-to-answer skip and resume restore all cover it), and draws it with
the clarify card's shell, key handling and confirm bar. Kind question
uses the clarify question block. Accent, theme and layout reuse today's
onboarding swatches, the settings mode labels and the layout preview
cards, and apply the pick live. Connectors (read on the account owner,
since the setup profile has no manage_connections) and plugins use the
onboarding chips, with a now / later / save control per picked row when
intent is on. The answer returns {picked, intent} on P15's wire; Skip
returns {} (cancelled).
start_chat shows the new chat's title and profile with an Open button.
A live completion moves the user into the new chat only when the calling
chat is in the foreground; history and background completions never
move them. start_chat joins the backend lifecycle UI set so the card
shows with tool progress off.
Open decisions for review: accent and theme picks apply live only (the
accent override is not persisted, and the theme mode lands on the setup
profile); the theme card offers light, dark and system.
