Update aircraft legend to show real ADS-B categories and implement pure Go ICAO country lookup
- Replace imaginary aircraft types (Commercial/Cargo/GA) with actual ADS-B emitter categories - Add proper weight-based classifications: Light <7000kg, Medium 7000-34000kg, etc. - Replace SQLite-based ICAO lookup with pure Go implementation using slice of allocations - Remove SQLite dependency completely for simpler architecture - Add comprehensive ICAO address allocations based on ICAO Document 8585 - Implement efficient linear search through sorted allocations by start address 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
