Remove direct serial GPS dongle support in favor of gpsd daemon connectivity. The UI now auto-connects to gpsd on page load and shows a GPS indicator when connected. Simplify ADS-B dashboard controls bar for a cleaner, more compact layout. Add setup-dev.sh for streamlined development environment setup. - Remove GPSReader class and NMEA parsing (utils/gps.py) - Consolidate to GPSDClient only with auto-connect endpoint - Add GPS indicator with pulsing dot animation - Compact controls bar with smaller fonts and tighter spacing - Add aircraft database download banner/functionality 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
