Adds advanced visual feedback system for 3D radar aircraft with real-time signal quality indicators:
Signal Quality Visualization:
- Opacity mapping based on signal strength (-60 to -5 dBFS range)
- Emissive glow intensity reflects signal quality (Excellent/Good/Fair/Poor)
- Multi-source data indicators (small spheres for aircraft with multiple receivers)
- Dynamic signal strength analysis from aircraft sources data
- Real-time updates with changing signal conditions
Enhanced Trail System:
- Gradient coloring with age-based fading (30% to 100% intensity)
- Aircraft type-based trail colors (cyan=helicopter, blue=heavy, yellow=light, teal=medium)
- Signal quality affects trail brightness and visibility
- Custom BufferGeometry with per-vertex colors
- Memory-efficient geometry disposal and rebuilding
Technical Improvements:
- Modular signal data extraction from aircraft sources
- Linear signal strength to opacity mapping
- Quality multiplier system for visual feedback
- Proper Three.js BufferAttribute management
- Dynamic visual updates synchronized with aircraft data
Visual Results:
- Strong signals = bright, opaque aircraft with vivid trails
- Weak signals = dim, transparent aircraft with faded trails
- Multi-source aircraft display small indicator spheres
- Trail colors match aircraft types for consistency
- Smooth gradient effects enhance flight path visualization
Addresses core signal quality and trail enhancement requirements from issue #42.

The embedded files debug output was showing on every database page visit,
cluttering the logs with unnecessary information. Made it conditional on
the -verbose flag to reduce noise in production logs.
Changes:
- Added 'debug' field to Server struct
- Updated NewWebServer constructor to accept debug parameter
- Pass verbose flag from main.go to server constructor
- Made debugEmbeddedFiles() conditional on debug flag
Now debug output only appears when -verbose flag is used, keeping
normal operation clean while preserving debugging capability.

- Database initialization succeeds
- skyview-data status command works
- Main skyview server starts with database connection

Replaced github.com/mattn/go-sqlite3 (CGO-based) with modernc.org/sqlite
(pure Go implementation) to enable CGO-free builds while maintaining
full SQLite functionality.
Benefits:
- ✅ Cross-compilation without C compiler requirements
- ✅ Simplified build environment (no CGO_ENABLED=1)
- ✅ Reduced deployment dependencies
- ✅ Easier container builds and static linking
- ✅ Full SQLite compatibility maintained
Changes:
- Updated go.mod to use modernc.org/sqlite v1.34.4
- Updated database import to use pure Go SQLite driver
- Removed CGO_ENABLED=1 from all Makefile build targets
- Verified all binaries (skyview, beast-dump, skyview-data) build successfully
The modernc.org/sqlite package is a cgo-free port of SQLite that transpiles
the original C code to Go, providing identical functionality without CGO.

Added missing icon types (heavy, large, light, medium) to the loadIcons() function.
The icon cache was only loading 6 out of 10 available SVG icons, causing aircraft
with weight-based classifications to display as plain circles instead of proper
aircraft icons.
Fixed icon types now loaded:
- ✅ commercial, helicopter, military, cargo, ga, ground (existing)
- ✅ heavy, large, light, medium (newly added)
This ensures all aircraft with known ADS-B emitter categories display the correct
type-specific icons instead of falling back to generic circle markers.

Fixes incorrect time calculations in the interface clocks:
UTC Clock Issues Fixed:
- Remove incorrect timezone offset addition that was causing wrong UTC display
- Use proper getUTCHours() and getUTCMinutes() methods directly on current time

- Run 'make format' to ensure all Go code follows standard formatting
- Maintains consistent code style across the entire codebase
- No functional changes, only whitespace and formatting improvements
- Updated legend to use the actual helicopter.svg design instead of abstract simplified version
- Now shows proper helicopter with main rotor, fuselage, cockpit, tail boom, tail rotor, and landing skids
- Much more recognizable as rotorcraft in the legend display
Resolves issue #13 by implementing comprehensive aircraft legend improvements:
## New Features
- **Size-based aircraft icons**: Created distinct SVG icons for light, medium, large, and heavy aircraft with progressively larger visual representations
- **Visual aircraft icons in legend**: Replaced colored squares with actual aircraft silhouettes showing relative sizes and types
- **Enhanced categorization**: Added military category to legend and improved icon selection logic
## Improvements
- **Better differentiation**: Each weight class now has a unique icon shape, not just color
- **Accurate ADS-B mapping**: Icons correctly map to decoded ADS-B emitter categories
- **Clearer legend display**: Users can now see actual aircraft shapes instead of generic colored rectangles
## Technical Changes
- Created 4 new SVG icons: light.svg, medium.svg, large.svg, heavy.svg
- Updated legend HTML to embed aircraft SVG icons inline
- Enhanced JavaScript logic to better match categories to appropriate icon types
- Simplified color mapping function for cleaner code
This addresses the original concerns about confusing legend entries and lack of visual differentiation between aircraft types.
