Resolves issue #3 where aircraft age field was always showing 0 seconds.
Backend Changes:
- Fix MarshalJSON in merger.go to calculate age dynamically using time.Since(a.LastUpdate)
- Add comprehensive tests for age calculation in merger_test.go
Frontend Changes:
- Add calculateAge() utility method to both aircraft-manager.js and ui-manager.js
- Update popup content and aircraft table to use client-side age calculation
- Implement real-time age updates every second in app.js
- Add updateOpenPopupAges() function to refresh popup displays
Key Benefits:
- Aircraft age now shows actual seconds since last transmission
- Real-time updates in UI without requiring new WebSocket data
- Proper data staleness indicators for aviation tracking
- No additional server load - client-side calculation using last_update timestamp

- 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.

Added comprehensive support for VRS (Virtual Radar Server) JSON format
as a simpler alternative to Beast binary protocol, enabling integration
with readsb --net-vrs-port output.
## Key Features:
- **VRS JSON Parser**: Stream parsing of newline-delimited JSON aircraft data
- **VRS Client**: TCP client with automatic reconnection and error recovery
- **Mixed Format Support**: Use Beast and VRS sources simultaneously
- **Enhanced Aircraft Data**: Added VRS-specific fields (registration, type, operator)
- **Position Source Tracking**: Identifies ADS-B, MLAT, TIS-B, and satellite positions
## Implementation:
- `internal/vrs/parser.go`: VRS JSON message parsing and validation
- `internal/client/vrs.go`: VRS TCP client implementation
- Enhanced `MultiSourceClient` to support both Beast and VRS formats
- Extended `Aircraft` struct with validity flags and additional metadata
- Updated configuration to include `format` field ("beast" or "vrs")
## Testing:
- Successfully tested against svovel:33005 VRS JSON stream
- Verified aircraft data parsing and position tracking
- Confirmed mixed-format operation with existing Beast clients
## Documentation:
- Updated README.md with VRS format configuration examples
- Enhanced ARCHITECTURE.md with VRS parser documentation
- Added data format comparison and configuration guide
This enables simpler integration with modern readsb installations while
maintaining full backward compatibility with existing Beast deployments.

Fixes#22: Improve Debian package changelog to show incremental version history
The Debian package changelog now includes the complete version history
instead of just changes since the previous release. This provides users
with full visibility into the software's evolution when reviewing
package updates.
Changes:
- Rewrote changelog generation to iterate through all git tags
- Generate entries for each tagged version in reverse chronological order
- Include current development version if commits exist after latest tag
- Fixed shellcheck warnings for better script quality
- Added -f flag to gzip to force overwrite existing changelog.gz files
Benefits:
- Complete version history visible in every package
- Standard Debian changelog format compliance
- Better integration with apt changelog and dpkg tools
- Improved transparency for users reviewing updates
- Proper audit trail for administrators
The changelog now shows all versions with their respective changes,
making it easier for users to understand what has changed between
their installed version and the available update.

The official Debian repositories already contain a package named
"skyview" which is associated with NASA's SkyView Virtual Observatory
(https://skyview.gsfc.nasa.gov/), a tool for astronomical data
visualization.
To avoid package naming conflicts and potential confusion for users,
this commit renames our ADS-B aircraft tracking application package
to "skyview-adsb". This clearly indicates the package's purpose
(ADS-B tracking) while maintaining the SkyView brand identity.
Changes:
- Package name: skyview → skyview-adsb
- System user/group: skyview → skyview-adsb
- Config directory: /etc/skyview → /etc/skyview-adsb
- Data directory: /var/lib/skyview → /var/lib/skyview-adsb
- Log directory: /var/log/skyview → /var/log/skyview-adsb
- Systemd service: skyview.service → skyview-adsb.service
- Documentation path: /usr/share/doc/skyview → /usr/share/doc/skyview-adsb
The binaries (/usr/bin/skyview and /usr/bin/beast-dump) remain
unchanged as they don't conflict at the filesystem level.
This ensures clean installation alongside any existing skyview
packages and prevents apt/dpkg conflicts during installation.

This addresses Issue #18 by correcting the CPR global decoding algorithm
implementation that was causing aircraft to appear tens of kilometers
east of their actual positions.
Root Cause:
- CPR longitude zone calculation always used NL-1 regardless of frame type
- Specification requires: even frames use NL zones, odd frames use NL-1 zones
- This caused systematic eastward displacement for all aircraft positions
Changes:
- Implement frame-consistent zone calculations per RTCA DO-260B specification
- Even frame (i=0): ni = max(1, NL - 0) = max(1, NL)
- Odd frame (i=1): ni = max(1, NL - 1)
- Add comprehensive documentation with authoritative source references
- Ensure latitude and longitude use same frame choice for consistency
Testing:
- Aircraft south of Oslo now appears correctly (was near Skarlandsvatnet)
- Aircraft north of Oslo should now appear correctly (was east of Lillestrøm)
- Systematic eastward bias eliminated
