"""API-server reasoning-effort request parsing accepts the full ladder.

_request_reasoning_config() previously whitelisted only none..xhigh, so an
API/browser client sending ``max`` or ``ultra`` (both valid /reasoning and
config.yaml levels) was silently ignored and the session ran at the default
effort. The server now accepts the full internal ladder; per-provider wire
clamping happens downstream in the transports/profiles via
agent.reasoning_effort (#78216's api_server observation).
