* feat(config): add configurable pacing controls for slow/local LLM workloads (#2963)
Add a new `[pacing]` config section with four opt-in parameters that
let users tune timeout and loop-detection behavior for local LLMs
(Ollama, llama.cpp, vLLM) without disabling safety features entirely:
- `step_timeout_secs`: per-step LLM inference timeout independent of
the overall message budget, catching hung model responses early.
- `loop_detection_min_elapsed_secs`: time-gated loop detection that
only activates after a configurable grace period, avoiding false
positives on long-running browser/research workflows.
- `loop_ignore_tools`: per-tool loop-detection exclusions so tools
like `browser_screenshot` that structurally resemble loops are not
counted toward identical-output detection.
- `message_timeout_scale_max`: overrides the hardcoded 4x ceiling in
the channel message timeout scaling formula.
All parameters are strictly optional with no effect when absent,
preserving full backwards compatibility.
