- Add fly.private.toml template for deployments with no public IP
- Add "Private Deployment (Hardened)" section to Fly docs
- Document how to convert existing deployment to private-only
- Add security notes recommending env vars over config file for secrets
This addresses security concerns about Clawdbot gateways being
discoverable on internet scanners (Shodan, Censys). Private deployments
are accessible only via fly proxy, WireGuard, or SSH.

* fix(voice-call): prevent audio overlap with TTS queue
Add a TTS queue to serialize audio playback and prevent overlapping
speech during voice calls. Previously, concurrent speak() calls could
send audio chunks simultaneously, causing garbled/choppy output.
Changes:
- Add queueTts() to MediaStreamHandler for sequential TTS playback
- Wrap playTtsViaStream() audio sending in the queue
- Clear queue on barge-in (when user starts speaking)

* fix(voice-call): use iterative queue processing to prevent heap exhaustion
The recursive processQueue() pattern accumulated stack frames, causing
JavaScript heap out of memory errors on macOS CI. Convert to while loop
for constant stack usage regardless of queue depth.
* fix: prevent voice-call TTS overlap (#1713) (thanks @dguido)
