Add persistent DuckDB storage to the proxy
CareLink responses normally expose only a rolling history window of about 24 hours. Persisting each successful proxy download preserves readings and pump events after they leave that window.
DuckDB is used because it is embedded and file-based: the proxy can write a local database without operating a separate database server. It also supports SQL queries over the retained snapshots and history when analysis is needed.
Changes
duckdbas a Python dependency.CareLinkStorage, which stores complete API responses incarelink_snapshotsand de-duplicated history records incarelink_history.--databaseto select the database path; by default,carelink.duckdbis created beside the token file.
