// "auto" → Prefer on-device Apple Foundation Models when available, else detect an
// installed AI CLI (claude > codex > gemini > opencode), skip if none found (default)
// "none" → Skip summarization — Claude summarizes via MCP when asked
// "apple" → Apple Foundation Models, fully on-device (macOS 26+ with Apple Intelligence)
// "agent" → Agent CLI (claude -p, codex exec, gemini -p, opencode run, pi -p) — uses existing subscription, no API key
// "ollama" → Local Ollama server (no API key needed)
// "claude" → Anthropic Claude API (ANTHROPIC_API_KEY env var, legacy)
// "openai" → OpenAI API (OPENAI_API_KEY env var, legacy)
// "mistral" → Mistral API (MISTRAL_API_KEY env var)
// "openai-compatible" → OpenAI-compatible chat completions endpoint
//
// For long transcripts: map-reduce chunking.
// Chunk by time segments → summarize each chunk → synthesize final.
