NutriTrace

Added

• Local Open Food Facts mirror (self-hoster opt-in, env-gated). Point NutriTrace at a local DuckDB copy of OFF and barcode + name lookups hit it first for instant, network-free responses. Stale-mirror false negatives auto-heal by falling through to the public OFF API on a miss, so a week-old mirror still feels live. True air-gap mode (OFF_LOCAL_ONLY=1) blocks all remote traffic, including OFF account uploads. See DEPLOY.md → Local Open Food Facts mirror for the full setup. (Issue #22)
• In-app refresh control for the OFF mirror. Settings → Connected Services → Open Food Facts (admin only) shows mirror size, last refresh, and an Auto-Refresh schedule (Off / Daily / Weekly / Monthly, default Weekly). A Refresh Now button kicks an immediate full download with live progress in the banner. Initial download happens automatically on first boot when the env var is set; no manual wget required. Refreshes use atomic swap, so no container restart is needed and a failed mid-flight download never corrupts the running mirror.
• Connection status banner for push notifications, matching the pattern used by USDA / Mealie / AI / Wellness integrations. Top-of-card pill shows the configured provider; a Send Test button posts a test notification through whichever delivery method is active.

Changed

• Sleep score tuning. Very short nights (under 5 hours) no longer balloon the deep+REM percentage above realistic ceilings (35% under 5h, 40% under 6h), bringing calculated scores closer to Fitbit's own.
• About → Disclaimer strengthened. Spells out the medical conditions NutriTrace is not designed for (diabetes, eating disorders, allergies, pregnancy, breastfeeding, pediatric needs, kidney/liver disease, metabolic disorders), and underscores that Trace AI answers and Open Food Facts data can be incorrect.

Fixed

• Bulk-imported foods now sync immediately to Android. After a successful bulk import on server-connected Android, the app triggers a full sync so the foods appear in the foods tab without waiting 30-60 seconds for the periodic sync. (Issue #39 followup)
