Add a "send now" button to queued AI-chat messages: it interrupts the
running agent and immediately sends that message, while the agent's
partial output at interruption is kept in history and the next turn is
marked as a user interrupt.
Client:
- queue-helpers: pure `promoteToHead` to move a queued message to the head.
- chat-thread: `sendNow` (promote head + abort + flush-on-abort), one-shot
`flushOnAbortRef`/`interruptNextSendRef`, `interrupted` flag in the
request body, and the "send now" ActionIcon in the queued list.
Server:
- `interrupted` on AiChatStreamBody; pure `isInterruptResume` confirms the
client hint against persisted history (prev assistant turn aborted/
streaming) before honouring it.
- prompt: INTERRUPT_NOTE injected in the context section only on a
confirmed interrupt-resume turn so the model treats the partial answer
above as incomplete.
Tests: promoteToHead, chat-thread send-now (abort + resend + one-shot
interrupt flag + non-streaming immediate send), isInterruptResume, and
the prompt interrupt-note injection.

Previously a message composed while the AI agent was streaming a reply was
silently dropped (the composer early-returned on isStreaming). Now such
messages are queued FIFO and sent automatically once the current turn
finishes cleanly.
- chat-input: submit() enqueues while streaming (via new onQueue prop) and
sends otherwise; during streaming show a queue Send button (when text is
present) alongside the Stop button; the textarea stays usable.
- chat-thread: per-conversation queue in local state (mirrored in a ref);
flush the next message in onFinish ONLY on a clean finish - ai@6 useChat
fires onFinish from a finally on Stop/disconnect/error too, where the queue
must be preserved. Pending messages render as removable chips above the
composer. Queue is cleared on chat switch (parent remount) and survives
in-place new-chat id adoption.
- queue-helpers: pure FIFO helpers (enqueue/dequeue/removeQueuedById) + tests.
- i18n: add en-US/ru-RU keys (Queue message, Remove queued message,
Send when the agent finishes).
