Fixes TypeScript compilation error (TS2352) in src/agents/pi-embedded-runner-extraparams.test.ts by adding missing required fields to a Model<"openai-responses"> mock object. The test was failing because the mock object with a compat field didn't sufficiently overlap with the expected type shape.

Changes:

• Added name, reasoning, input, cost, contextWindow, and maxTokens fields to the mock object in the supportsStore=false regression test
• All added fields align with ModelDefinitionConfig type requirements from src/config/types.models.ts
• Change is test-only and doesn't affect production code

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The change is a minimal, well-scoped TypeScript typing fix in a test file. It adds required fields to a mock object to satisfy type constraints without altering any test logic or production code. The fix follows existing patterns in the codebase and correctly addresses the TS2352 compilation error.
• No files require special attention
