Chatify 0.2.4

Composer actions swap by context: dictate button when the box is empty, send once you type (with a speech-capable browser), send always present while an answer streams.

Controls announce their current state: the source scope button and every custom dropdown now speak their value (for example, "Answer depth: Standard").

Keyboard shortcuts are exposed to assistive technology with aria-keyshortcuts (send, previous/next question, chat search).

Question box accessible name is now a full instruction; a sources-and-citations line joins the composer footer.

Answers now render fenced code blocks, each with its own Copy code button.

Repaired stale strict UI tests (stream stop/retry, chat lifecycle, deleted chat topics) to match the current toast and sidebar behaviour.
