Smarter LQI filtering, better defaults

Changes

• LQI filtering scoped to neighbor links only — both remove and dim modes now only affect neighbor (non-routing) links. Backbone and route links always keep their full style regardless of LQI value. This fixes a bug where backbone links with low LQI were incorrectly styled as dim/weak.

• Updated defaults for better out-of-the-box visuals:

  • min_lqi: 0 → 50
  • min_lqi_mode: dim → remove
  • route_opacity: 0.7 → 0.8
  • neighbor_opacity: 0.3 → 0.6
  • dim_opacity: 0.25 → 0.1

• Renamed JS file zigbee-mesh-map.js → ha-zigbee-mesh-map.js to match HACS requirements.

Docs

• Added recorder exclusion tip to avoid the State attributes exceed maximum size warning in HA logs.
