[Feature]: Unlimited generation timeout

Problem / pain point

I am using local LLM's for confidentiality reasons. They are too slow for the timeouts offered in the GUI, 2 hours. I would like timeouts like 10 hours, or perhaps even unlimited. I usually run those generation jobs over-night, and I would prefer them to complete correctly than being stopped unnecessarily.

Proposed solution

Either add more timeout options or way to disable the timeout.

Alternatives considered

I could buy faster hardware, but since it will likely get old and too small too fast, I would prefer to use the hardware I have.

Scope

Generation capability

Hard-constraints check

• I have read the hard constraints in CLAUDE.md and this proposal does not conflict with any of them.
