- Replaced native `AbortSignal.timeout` calls with self-clearing timeout helper functions across model discovery.
- Added `withTimeoutSignal`, `withCatalogDiscoveryTimeout`, and `withOpenAICompatibleDiscoveryTimeout` helpers to manage cancellable fetch timeouts.
- Supported `timeoutMs` options throughout the Ollama, Llama.cpp, LiteLLM, vLLM, LM Studio, and OpenAI-compatible discovery processes.
- Documented the fix addressing Bun garbage collection segfaults caused by uncancellable timeout signals.
