v0.4.0

What's Changed

• Migrate heatmap routes path to /api/internal/fragment/data/heatmap/routes (legacy URLs auto-rewritten)
• Cache route payloads in the service worker (memory + session TTL, ETag) for faster re-enable
• Style-only updates no longer re-fetch or rebuild full geometry
• Normalize coordinates once to GeoJSON [lng, lat] with chunked processing
• MapLibre/Mapbox: setData / setPaintProperty instead of full overlay rebuilds
• OSM iD: rAF-throttled hover, spatial grid hit-testing, viewport-culled and zoom-simplified SVG redraws
