Rust groups.rs ProjectConfig was missing provider, model, and other optional
fields — serde silently dropped them on save, causing all projects to fall
back to claude/Opus on reload. Added all missing fields to both ProjectConfig
and GroupAgentConfig structs.
Rewrote aider-runner from one-shot --message mode to interactive stdin/stdout:
- Persistent aider process with multi-turn conversation support
- Pre-fetches btmsg inbox and bttask board before sending prompt to LLM
- Autonomous agent override prompt so LLM acts instead of asking for files
- Line-buffered output (no token-by-token fragments)
- Thinking block classification for DeepSeek R1
- Graceful /exit shutdown
