feat:Add ChatReasoningSettings and reasoning to chat types in openapi.yaml

[HavenDV]

Summary by CodeRabbit

• New Features
  • Added optional “reasoning” settings to chat requests and individual user messages, enabling you to toggle reasoning on/off and choose effort levels (low, medium, high).
  • Provides finer control over response depth and trade-offs between quality, latency, and cost.
  • Backward compatible: existing integrations work unchanged if reasoning is not specified.

Poem

A bunny tweaks the schema file,
Adds “reasoning” with measured style.
Low, medium, high—efforts aligned,
Toggle on, or leave behind.
Hop, hop—the YAML sings,
Clear paths for thoughtful things.

5554-5571: LGTM – new schema is well-scoped.

ChatReasoningSettings cleanly models the feature toggle and effort level.

---

7549-7550: LGTM – property wiring matches the new schema.

reasoning now references ChatReasoningSettings, keeping the request surface coherent.
