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.

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

The decoder was capping all speeds at 600kt before validation, which caused:
1. Corrupt helicopter data to show false 600kt readings
2. Legitimate high-speed aircraft to be incorrectly limited
3. Validation logic in merger to miss corrupt data detection
The merger already has proper speed validation at 2000kt (Mach 3) and
position-based validation that catches impossible speeds from corrupt data
regardless of aircraft type.

**Transponder Display - WORKING ✅**
- Fixed: TransponderCapability now appears in popup (showing "Enhanced", "Level 2+", etc.)
- Added transponder field handling in merger.go mergeAircraftData()
- Shortened labels: "Level 2+" instead of "Level 2+ Transponder"
- Shows in popup when DF11 All-Call Reply messages are received
**Signal Quality Implementation - IN PROGRESS ⚠️**

**Next Steps:**
- Debug why SignalQuality field remains empty in API responses

**Transponder Display Improvements:**
- Simplified transponder capability labels to be more concise
- "Level 2+ Transponder" → "Level 2+"
- "Enhanced Transponder" → "Enhanced"
- "Alert/Emergency Status" → "Alert/Emergency"
- Removes redundant "Transponder" suffix for cleaner popup display
**New Signal Quality Feature:**
- Added SignalQuality field combining NACp, NACv, and SIL into human-readable assessment
- Quality levels: "Excellent", "Good", "Fair", "Poor" based on aviation standards
- Prioritizes surveillance integrity (SIL) then position accuracy (NACp)
- Automatically calculated when operational status messages (TC 31) are received
- Displayed in aircraft popup when available
**Signal Quality Algorithm:**
- **Excellent**: High integrity (SIL ≥ 2) with precise position (NACp ≥ 9)
- **Good**: Good integrity with moderate accuracy OR very high accuracy
- **Fair**: Some integrity with basic accuracy OR high accuracy without integrity
- **Poor**: Low but usable quality indicators
- **Empty**: No quality data available
**Frontend Enhancements:**
- Added "Signal Quality" row to aircraft popup
- Only displays when quality data is available
- Clean integration with existing popup layout
- Shows alongside transponder information
**Data Quality Context:**
- NACp: Position accuracy (0-11, higher = more precise location)
- NACv: Velocity accuracy (0-4, higher = more precise speed/heading)
- SIL: Surveillance integrity (0-3, higher = more reliable data)
This gives users a quick understanding of data reliability without needing
to interpret technical NACp/NACv/SIL values directly.

Add dedicated transponder fields to prevent Mode S decoder from overwriting
the aircraft Category field with transponder capability information.
**Problem Fixed:**
- DF11 All-Call Reply messages were setting aircraft.Category to "Enhanced Transponder"
- This overwrote the actual aircraft type (Light, Medium, Heavy, etc.) from ADS-B
- Users saw "Enhanced Transponder" instead of proper aircraft classification
**Solution:**
- Added dedicated TransponderCapability and TransponderLevel fields to Aircraft struct
- Updated JSON marshaling to include new transponder fields
- Modified decodeAllCallReply() to use dedicated fields instead of Category
- Enhanced popup display to show transponder info separately from aircraft type
- Removed Category overwriting in decodeCommD() for DF24 messages
**New Aircraft Fields:**
- TransponderCapability: Human-readable capability description
- TransponderLevel: Numeric capability level (0-7)
**Popup Display:**
- Aircraft type now shows correctly (Light, Medium, Heavy, etc.)
- Transponder capability displayed as separate "Transponder:" field when available
- Only shows transponder info when DF11 messages have been received
**Data Quality Indicators Clarification:**
- NACp: Navigation Accuracy Category - Position (0-11, higher = more accurate)
- NACv: Navigation Accuracy Category - Velocity (0-4, higher = more accurate)
- SIL: Surveillance Integrity Level (0-3, higher = more reliable)
Users now see both proper aircraft classification AND transponder capability
information without conflicts between different message types.

Add comprehensive position validation to filter out impossible aircraft
movements and improve trail accuracy as requested in issue #16.
**Position Validation Features:**
- Geographic coordinate bounds checking (lat: -90 to 90, lon: -180 to 180)
- Altitude validation (range: -500ft to 60,000ft)
- Speed validation (max: 2000 knots ≈ Mach 3)
- Distance jump validation (max: 500 nautical miles)
- Time consistency validation (reject out-of-order timestamps)
- Speed consistency warnings (reported vs. implied speed)
**Integration Points:**
- updateHistories(): Validates before adding to position history (trails)
- mergeAircraftData(): Validates before updating aircraft position state
- Comprehensive logging with ICAO identification for debugging
**Validation Logic:**
- Rejects obviously wrong positions that would create impossible flight paths
- Warns about high but possible speeds (>800 knots) for monitoring
- Maintains detailed logs: [POSITION_VALIDATION] ICAO ABCDEF: REJECTED/WARNING
- Performance optimized with early returns and minimal overhead
**Result:**
- Users see only realistic aircraft trails and movements
- Obviously wrong ADS-B data (teleporting, impossible speeds) filtered out
- Debug logs provide visibility into validation decisions
- Clean flight tracking without zigzag patterns or position jumps
