The Go side already forwards the request's effort as
Metadata["reasoning_effort"], but the sglang backend only read
enable_thinking: every level got the same model-level thinking_budget,
so low/medium/high produced identical reasoning.
- New model option `effort_budgets:low=…;medium=…;high=…` picks the
budget of the request's level; unlisted levels and requests without an
effort keep `thinking_budget`. Parsing reuses _parse_thinking_budget.
- A level listed in effort_budgets turns reasoning on for that request,
so levels the Go side does not know cannot silently disable it.
- ApplyReasoningEffort now treats `xhigh` and `max` as thinking levels.
Before, they left DisableReasoning unset, so with a model default of
"off" asking for more reasoning produced none.
