v0.3.0

• where_to_touch_grass takes place: known neighborhoods resolve offline, anything else is geocoded once via OpenStreetMap Nominatim and pinned
• park list: top 5 with distances
• Overpass mirror failover (overpass-api.de, then kumi.systems)
• --demo mode: canned weather, location and spots, zero network calls
• .mcpb bundle for Claude Desktop, attached
• indoor tolerance now defaults to 2 minutes; pass threshold_minutes for clemency
