- Updated all references from v6 to v7 for `github.com/router-for-me/CLIProxyAPI`.
- Ensured consistency in imports within core libraries, tests, and integration tests.
- Added missing tests for new features in Redis Protocol integration.
Address two blocking issues from PR review:
- Auth file now named vertex-{prefix}-{project}.json so importing the
same project with different prefixes no longer overwrites credentials
- Prefix containing "/" is rejected at import time instead of being
silently ignored at runtime
- Add prefix to in-memory metadata map for consistency
