zerone0x bc52d4a459 fix(openrouter): skip reasoning effort injection for 'auto' routing model
The 'auto' model on OpenRouter dynamically routes to any underlying model
OpenRouter selects, including reasoning-required endpoints. Previously,
OpenClaw would unconditionally inject `reasoning.effort: "none"` into
every request when the thinking level was "off", which causes a 400 error
on models where reasoning is mandatory and cannot be disabled.

Root cause:
- openrouter/auto has reasoning: false in the built-in catalog
- With thinking level "off", createOpenRouterWrapper injects
  `reasoning: { effort: "none" }` via mapThinkingLevelToOpenRouterReasoningEffort
- For any OpenRouter-routed model that requires reasoning this results in:
  "400 Reasoning is mandatory for this endpoint and cannot be disabled"
- The reasoning: false is then persisted back to models.json on every
  ensureOpenClawModelsJson call, so manually removing it has no lasting effect

Fix:
- In applyExtraParamsToAgent, when provider is "openrouter" and the model
  id is "auto", pass undefined as thinkingLevel to createOpenRouterWrapper
  so no reasoning.effort is injected at all, letting OpenRouter's upstream
  model handle it natively
- Add an explanatory comment in buildOpenrouterProvider clarifying that the
  reasoning: false catalog value does NOT cause effort injection for "auto"

Users who need explicit reasoning control should target a specific model
id (e.g. openrouter/deepseek/deepseek-r1) rather than the auto router.

Fixes #24851
