Bump CHANGELOG section to [1.1.1] for the launch tag

GitHub's immutable releases feature reserves the v1.1.0 tag name even
after the release is deleted. The 25-minute v1.1.0 lifecycle (tagged,
broken docker-publish, deleted) was never user-visible, but the tag
name is permanently locked on origin. Ship as v1.1.1 instead. The
release content is unchanged from what the [1.1.0] section described.

 Local Mode lands. Run the LLM, voice synthesis, and transcription on your own machine, each piece flipping independently. Plus the marketing site migration to Astro for sub-second first paint, plus two companion OSS repos that package the voice servers as standalone projects.

 ### Added
 
 - **Local Mode panel with per-service toggles for LLM, TTS, and STT.** Each runs independently, so a BYOK-LLM user can still route voice through local containers. Settings → AI Model → Local Mode. The LLM toggle routes to any OpenAI-compatible endpoint (LM Studio, Ollama, vLLM, llama.cpp). The TTS toggle routes to local Kokoro (EN) and Qwen3-TTS (DE). The STT toggle routes to local Whisper. With all three on plus a local LLM, your conversation stays on your machine.
