fix(oneshot): honor configured auxiliary.<task>.timeout in run_oneshot (residual of #56322)

[hashbender]

Follow-up to merged NousResearch#56322 (which fixed the same auxiliary.<task>.timeout bug class, NousResearch#32729, for the generate_title sibling).

The residual

agent/oneshot.py::run_oneshot hard-coded timeout: float = 60.0 in its signature and forwarded it to call_llm. The live llm.oneshot JSON-RPC handler (tui_gateway/server.py) calls run_oneshot(task=task, ...) and never passes a timeout, so 60.0 was always forwarded. But call_llm only reads auxiliary.<task>.timeout from config when it's called with timeout=None:

effective_timeout = timeout if timeout is not None else _get_task_timeout(task)

So a configured auxiliary.<task>.timeout was silently ignored on the entire live llm.oneshot path — the exact shape of NousResearch#32729 that NousResearch#56322 just fixed for generate_title (which now uses timeout: Optional[float] = None), left unfixed on this sibling.

Fix

Default run_oneshot's timeout to None and resolve it the same way call_llm does when the caller passes nothing:

effective_timeout = timeout if timeout is not None else _get_task_timeout(task, default=60.0)

• Configured auxiliary.<task>.timeout is now honored on the llm.oneshot path.
• An explicit timeout= from a caller is still forwarded verbatim (incl. 0.0, since the check is is not None).

Deliberate choice — no behavior change for unconfigured callers: I resolve with default=60.0 rather than letting call_llm apply its _DEFAULT_AUX_TIMEOUT of 30s, so callers that neither pass a timeout nor configure the task keep the historical 60s oneshot default. If you'd rather align run_oneshot fully with the auxiliary system's 30s default (dropping the bespoke 60s), that's a one-token change (default=60.0 → drop the arg) — I kept it non-regressive by default.

Tests

Added to tests/agent/test_oneshot.py:

• configured task timeout reaches call_llm (the regression),
• unconfigured falls back to 60s,
• an explicit timeout= is forwarded and skips resolution.
