This fix adds CLIProxyAPI-compatible random project ID generation when loadCodeAssist API fails to return a project ID. This allows FREE tier users to use the API without RESOURCE_PROJECT_INVALID errors.
Changes:
1. Added generateRandomProjectId() function matching CLIProxyAPI implementation
2. Changed fallback from empty string "" to generateRandomProjectId()
3. Cache all results (not just when projectId exists)
4. Removed unused ANTIGRAVITY_DEFAULT_PROJECT_ID import
