Fix: unify Zod version across workspaces + migrate OpenAI API to resp…

[dev107]

This PR fixes the build failure caused by two issues:

1. Deprecated OpenAI API
   The code used beta.chat.completions.parse, which no longer exists in the current OpenAI SDK.
   Updated to the new responses.parse API, including the required input/message structure.

2. Zod version mismatch across workspaces
   Several packages used different Zod versions, causing TS type incompatibilities during tsc -b.

   • Added a single Zod version via resolutions in the root package.json
   • Converted workspace Zod usage to peerDependencies + devDependencies for proper deduplication

Result

• tsc -b runs cleanly
• Docker build succeeds
• OpenAI functionality is now aligned with the latest SDK
• No unrelated files were modified
