feat: Kith voice sidecar + backend TTS wiring for Kaori#1
Merged
Conversation
Adds kith-voice/ Bun service that bridges Kith's PipecatRuntime to browser WebSocket clients for streaming ElevenLabs TTS. The backend dm.js route now fires a POST to the Kith voice service after emitting a bot message, keyed by the x-kith-session header from the web client.

Lockfile was missing transitive deps (https-proxy-agent, agent-base, debug, ms), causing `npm ci` to fail in CI. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Mechanical auto-fixes from `biome check --write --unsafe`: - Prefix unused params/vars with underscore - Convert string concatenation to template literals - Apply formatting (trailing commas, quotes, semicolons) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Convert assignment expressions in arrow callbacks to block bodies and re-format to satisfy biome check. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
