Ryan Malloy 7cae72b936 Graceful shutdown, blocking speak() with progress, and cancel support
speak() now blocks until playback finishes, reporting progress via SSE
(5% entry tone → 30% synthesis → 35-99% playing → 100% done). Entry
tone fires immediately on call to cover synthesis latency.

Queue shutdown waits for current speech to finish (configurable timeout,
default 30s) before draining pending items — no more mid-sentence
cutoffs on container restart.

Cancellation via cancel_speech() tool or MCP notifications/cancelled
kills pw-play and plays a vinyl scratch tone. Consumer continues to
next item after cancel.

Progress tracking uses a background ticker task instead of
asyncio.wait_for polling — the latter causes stale CancelledError
propagation to the consumer under Python 3.13.
