Default reasoning to on when model has reasoning: true (fix #22456) (#22513)

* Default reasoning to on when model has reasoning: true (fix #22456)

What: When a model is configured with reasoning: true in openclaw.json (e.g. OpenRouter x-ai/grok-4.1-fast), the session now defaults reasoningLevel to on if the user has not set it via /reasoning or session store.

Why: Users expected setting reasoning: true on the model to enable reasoning; previously only session/directive reasoningLevel was used and it always defaulted to off, so Think stayed off despite the model config.

* Chore: sync formatted files from main for CI

* Changelog: note zwffff/main OpenRouter fix

* Changelog: fix OpenRouter entry text

* Update msteams.md

* Update msteams.md

* Update msteams.md
