[Feature Request] Persistent Storage for Usage Statistics

[yuanyouyu]

Currently, usage statistics are stored in-memory only and reset on every container restart. This is problematic for container-based deployments (Docker, Kubernetes, Modal, etc.) where containers frequently restart or scale to zero.

Could you add an option to persist usage statistics to a SQLite database file, similar to how logs are handled with log-file-path?

this would be a great feature to add.
