[WIP] Fix TypeError: Client is not a constructor

[Copilot]

Fix TypeError: Client is not a constructor ✅

Issue Resolved: Users were encountering "TypeError: Client is not a constructor" when trying to use the SDK.

Root Cause: The SDK only exported DefaultApi but not a Client class, which is a common naming convention users expect.

Solution Implemented:

• Investigate the issue - confirmed Client export was missing
• Add Client export as alias to DefaultApi in api/apis.ts
• Rebuild and verify both Client and DefaultApi work correctly
• Update README.md with Client usage example showing both options
• Test comprehensive functionality (JS and TS)
• Run code review - no issues found
• Run security checks (CodeQL) - no vulnerabilities found
• Final verification - all tests pass

Changes Made:

1. Added export { DefaultApi as Client } in api/apis.ts
2. Updated README.md with example showing both Client and DefaultApi usage

Backward Compatibility:
✅ Fully backward compatible - existing code using DefaultApi continues to work
✅ Client and DefaultApi are identical (same class, just different export names)

Testing:
✅ JavaScript tests: Both constructors work correctly
✅ TypeScript tests: Type definitions are correct
✅ Integration tests: All API methods available on both
✅ Code review: No issues
✅ Security scan: No vulnerabilities

Security Summary:
No security vulnerabilities discovered or introduced by these changes. CodeQL analysis found 0 alerts.
