Resolve the remaining conflict in the Claude API request builder by preserving the contributor's Azure OpenAI response support while keeping main's explicit disabled-thinking handling and effort suppression.
Constraint: PR #21 was conflict-blocked against origin/main and maintainer edits are enabled on the fork branch
Rejected: Rebase the contributor branch | would rewrite a long external contribution history unnecessarily
Confidence: high
Scope-risk: moderate
Directive: Keep disabled-thinking effort suppression when changing provider request mapping
Tested: bun test tests/azureOpenAI.test.ts src/utils/__tests__/thinking.test.ts
Tested: bun run check:server
