* feat(analytics): upload web source maps to Sentry + tie release to build
Web crash reports were unusable: the bundle ships minified with no source
maps uploaded, and every build reported as the frozen APP_VERSION, so a
Sentry error showed an unreadable stack under a single release.
- Add @sentry/vite-plugin: emit hidden source maps and upload them by debug
id when SENTRY_AUTH_TOKEN is present (published Docker build only), then
delete the maps so they never ship. No-op for dev and the source archive.
- Set the Sentry release from SENTRY_RELEASE / VITE_SENTRY_RELEASE (the Docker
build passes the release version), falling back to APP_VERSION.
- Relax beforeSend so app bundle frames keep a host-stripped path (Sentry needs
it to match the uploaded map) while the instance hostname, error message, and
PII stay stripped. Filesystem paths still collapse to the basename.
- Wire the Dockerfile (sentry_auth_token build secret + SENTRY_RELEASE arg/env)
and the release docker job.
* fix(analytics): point source map upload at the snapotter org (project node)
