Track active Sender viewers from browser heartbeats and HLS IP fallback, filtering localhost access and exporting a low-cardinality plugin metric for Tribes rollups.
Extend the Docker origin/edge E2E harness with VictoriaMetrics/vmagent scraping and assertions for live /metrics export plus compact rollup storage. Update docs for the host metrics path.
Add flake outputs for the sender assets, packaged plugin, bundled Tribes release, and single-image Docker E2E target.
Update the Docker E2E runner to build that image through Nix with the local Tribes checkout override before running the origin/edge compose scenario.
