Add an in-app test that distinguishes baseline connectivity from GitHub and Hugging Face access, with actionable DNS, TLS, timeout, connection, and HTTP results.

• cb73690 feat(settings): add preference help tooltips

Add focusable question-mark tooltips for all learning preference labels and keep explanations out of the form layout.

• 615ac42 fix(review): reset session progress with daily plan

Count completed study and review items from today's restartable plan so a plan restart resets session progress without deleting learning history.

• e13c8e2 feat(reports): add retained daily learning summaries

Persist a daily report once planned learning and review are complete, show it from the home page and calendar, and let learners choose how long report details are retained without affecting card history.

• 0868474 perf(review): avoid repeated evaluation on rating

Reuse the server-side evaluation while the learner selects a rating, skip unchanged first-study card saves, and schedule backups after responses so advancing is not blocked by model inference or backup I/O.

• 61790a5 fix(tags): classify new card labels by language
