Telemetry Tracker v1.18.7

Fixed

• API: Hermes symbolication. React Native/Hermes stacks (including composed Hermes + packager source maps) now resolve to original source lines (#756).
• Monitoring: Sentry privacy guard. Our own operator Sentry setup (API and dashboard) pins privacy-preserving data collection so a future Sentry SDK v11 default change cannot broaden what is sent (#752).
• Docs: Railway self-hosters upgrading to v1.18.5+. apps/api/Dockerfile is auto-detected when a service's Root Directory is apps/api, which makes builds fail. Switch API/cron/worker services to Root Directory empty + Dockerfile apps/api/Dockerfile (docs/RAILWAY.md).

Changed

• Docs: Expo/EAS source maps guide for Hermes builds, and React Native SDK docs updates (#756).
• Docs and site: Web Vitals. LCP/INP/CLS/TTFB capture, webVitals: false, p75 and slow pages are now documented across SDK, Next.js and error-tracking pages (#757).
• Site: privacy copy. Privacy-by-default section on the Sentry alternative and migration pages (#753); privacy page lists the verified hosting region and processors (#755).
• No migrations. No env var changes.
