Function sendEvent

internal/llm/llm.go:343–350

sendEvent puts e on out, bailing if parent cancels first, so a slow or vanished consumer after Ctrl+C can't wedge the stream goroutine on a full buffer.

(parent context.Context, out chan<- Event, e Event)

	// retry-free: its job is fast feedback on a misconfigured profile.
	resp, errEvt := c.sendChat(parent, msgs, tools)
	for attempt := 0; errEvt != nil && attempt < len(c.RetryBackoff) && retryable(errEvt.Err); attempt++ {
		delay := c.RetryBackoff[attempt]
		hint := fmt.Sprintf("retry %d/%d in %s", attempt+1, len(c.RetryBackoff), delay)
		if !sendEvent(parent, out, Event{Kind: EventRetry, Content: hint, Err: errEvt.Err}) {
			return
		}
		select {
		case <-time.After(delay):
		case <-parent.Done():
			// Ctrl+C during the wait: unwind silently, exactly like a
			// cancelled sendEvent — the TUI already aborted the turn.
