Overview: Adds message editing and reasoning effort selection (instant/thinking) to Nova chat.

Issues found: None — this looks good to ship.

The regeneration flow is well-designed with a two-phase approach: truncate messages first, then send via useEffect once React has processed the state update. The refs (truncateFromMessageIdRef, pendingRegenerationRef, pendingSendSettingsRef) correctly preserve transient state across re-renders, and the setTimeout(0) pattern ensures the truncate ref is available during request preparation but cleared afterward.

Key implementation details I verified:

• The click-outside handler in ReasoningSelector properly cleans up its event listener on unmount
• Input validation in submitEdit prevents empty submissions
• Guard against sending during ongoing operations (status === "submitted" || status === "streaming")
• No XSS concerns since message content is rendered as text nodes, not innerHTML
• Model changes correctly reset reasoning effort to the default via getDefaultReasoningEffort()

Score: 9/10
