MapLibre-Port Runde 2: GL-Marker-Subsystem (map-gl-markers.js) + headless Test-Harness

Eigenständiges Modul: per-Kategorie GeoJSON-Cluster, rasterisierte Phosphor-Icons,
Danger-Polygone, Sichtbarkeit, Click→Popup. /maplibre-markers-test zum headless-Verifizieren
VOR dem Einbau in map.js (auth-gated).
