- Added metadata merge helpers in `sdk/cliproxy/auth` to retain existing auth-file settings while excluding token lifecycle fields.
- Applied merge before saving in management handler and `sdk/auth.Manager.Login` so re-login overwrites credentials without discarding user-configured fields.
- Updated token save paths for Claude, Codex, Kimi, XAI, and Vertex to persist merged metadata payloads when writing auth files.
Closes: #4945
- 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.
The logic for logging the path where credentials are saved was duplicated across several client implementations.
This commit refactors this behavior by creating a new centralized function, `misc.LogSavingCredentials`, to handle this logging. The `SaveTokenToFile` method in each authentication token storage struct now calls this new function, ensuring consistent logging and reducing code duplication.
The redundant logging statements in the client-level `SaveTokenToFile` methods have been removed.
- Updated imports and function calls to use `filepath` across all token storage implementations and server entry point.
- Ensured consistent handling of directory and file paths for improved portability.
