LLMProviderAdapter now tries all registered providers before giving up:
1. Named provider (if specified)
2. All 'fast' tier providers in order
3. All 'heavy' tier providers in order
4. Legacy active provider
Previously, if the first provider (e.g., vllm-local) failed, the adapter
threw immediately even though Anthropic and Gemini were available. Now it
logs the failure and tries the next candidate.

- Add warmup() to LlmProvider interface for eager subprocess startup
- ManagedVllmProvider.warmup() starts vLLM in background on project load
- ProviderRegistry.warmupAll() triggers all managed providers
- NamedProvider proxies warmup() to inner provider
- paginate stage generates LLM-powered descriptive page titles when
available, cached by content hash, falls back to generic "Page N"
- project-mcp-endpoint calls warmupAll() on router creation so vLLM
is loading while the session initializes
