chore: remove legacy copilot message endpoints

[nighca]

Summary

• remove the legacy Copilot message endpoints from the public OpenAPI spec
• simplify the frontend Copilot API to use /copilot/sse/message only
• hide the scope detail inside generateSSEMessage so callers only pass messages and options

Testing

• npx vitest --run src/apis/copilot.test.ts src/components/copilot/copilot.test.ts

Closes #2928

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on modernizing the Copilot integration by deprecating and removing older API endpoints and simplifying the client-side interaction. The changes consolidate message generation to a single, structured Server-Sent Events (SSE) endpoint, reducing complexity and improving maintainability of the Copilot feature.

Highlights

• API Endpoint Removal: Removed the legacy /copilot/message and /copilot/stream/message endpoints from the public OpenAPI specification, streamlining the Copilot API surface.
• Frontend API Simplification: Simplified the frontend Copilot API by removing the scope parameter from the generateSSEMessage function, now exclusively using /copilot/sse/message with a hardcoded 'standard' scope internally.
• Codebase Cleanup: Updated related test files and the main Copilot component to reflect the simplified generateSSEMessage signature, ensuring consistency and removing deprecated code.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Code Review

This pull request streamlines the Copilot API by removing the non-streaming /copilot/message and legacy /copilot/stream/message endpoints from the OpenAPI specification and client-side code. The CopilotScope type and generateMessage function are also removed. The generateSSEMessage function is updated to no longer require a scope parameter, hardcoding it to 'standard' for the /copilot/sse/message endpoint. Additionally, the /workflow/stream/message endpoint's response content type in the OpenAPI documentation is updated from application/stream to text/plain.

[Copilot]

Pull request overview

Removes legacy Copilot message endpoints from the documented/public API surface and simplifies the spx-gui Copilot API wrapper to only use the structured SSE endpoint.

Changes:

• Remove /copilot/message and /copilot/stream/message from docs/openapi.yaml (and remove rollout language referencing the legacy stream endpoint).
• Update the frontend Copilot message generation call path to use generateSSEMessage(messages, options) (scope no longer passed by callers).
• Update unit tests to match the updated generateSSEMessage signature and option type.

Clean, well-scoped removal. No dangling references to CopilotScope or generateMessage remain in the codebase, and all three mock classes in copilot.test.ts are updated consistently with the correct GenerateSSEMessageOptions type. Two minor nits: the hardcoded 'standard' scope string loses its type guard, and the /workflow/stream/message content-type fix should be verified against the actual response format.
