When both timeoutMs and a caller-provided abortSignal were set, the
timeout signal silently replaced the caller's signal. Now they are
combined via mergeAbortSignals() so either source can cancel the run.
Also removes dead array-handling branch in text-tool-extractor.ts
(extractJSONObjects only returns objects, never arrays).
Local models (Ollama, vLLM) sometimes return tool calls as text instead
of using the native tool_calls wire format. This adds a safety-net
extractor that parses tool calls from model text output when native
tool_calls is empty.
- Add text-tool-extractor with support for bare JSON, code fences,
and Hermes <tool_call> tags
- Wire fallback into OpenAI adapter chat() and stream() paths
- Add onWarning callback when model ignores configured tools
- Add timeoutMs on AgentConfig for per-run abort (local models can
be slow)
- Add 26 tests for extractor and fallback behavior
- Document local model compatibility in README
