- feat(chat): consolidate the per-session selectors (model, mode, agent settings) into a single cog dropdown with hover submenus on the message input action row, with the agent icon shown on the trigger and the dropdown labelled as "agent settings"; submenu widths are capped so long option lists no longer push the row off-screen. Localized across all 10 languages.
- feat(chat): move the folder and branch pickers out of the conversation context bar and into the message input action row, so workspace controls stay grouped with the input area where they're actually used.
- style(chat): widen the minimum tile width for tiled conversation tabs to 28rem so multi-tab layouts have more breathing room before content wraps.
- fix(acp): move conversation cancel-on-disconnect from the frontend to the backend lifecycle subscriber via a CAS update (in_progress → cancelled), so a concurrent user-driven completed or a prior pending_review from TurnComplete can no longer be silently overwritten. Eliminates the related frontend races (flash-disconnect during reconnect, dbConvIdRef dependency gap, post-unmount in-flight writes).
- fix(acp): raise the default CODEG_ACP_IDLE_TIMEOUT_SECS from 60s to 180s, giving the frontend keepalive (30s cadence) a 6× safety margin against network jitter and brief stalls before the backend reaps a connection.
