feat(phases 2-7): implement full GPS-denied navigation pipeline

Phase 2 — Visual Odometry:
  - ORBVisualOdometry (dev/CI), CuVSLAMVisualOdometry (Jetson)
  - TRTInferenceEngine (TensorRT FP16, conditional import)
  - create_vo_backend() factory

Phase 3 — Satellite Matching + GPR:
  - SatelliteDataManager: local z/x/y tiles, ESKF ±3σ tile selection
  - GSD normalization (SAT-03), RANSAC inlier-ratio confidence (SAT-04)
  - GlobalPlaceRecognition: Faiss index + numpy fallback

Phase 4 — MAVLink I/O:
  - MAVLinkBridge: GPS_INPUT 15+ fields, IMU callback, 1Hz telemetry
  - 3-consecutive-failure reloc request
  - MockMAVConnection for CI

Phase 5 — Pipeline Wiring:
  - ESKF wired into process_frame: VO update → satellite update
  - CoordinateTransformer + SatelliteDataManager via DI
  - MAVLink state push per frame (PIPE-07)
  - Real pixel_to_gps via ray-ground projection (PIPE-06)
  - GTSAM ISAM2 update when available (PIPE-03)

Phase 6 — Docker + CI:
  - Multi-stage Dockerfile (python:3.11-slim)
  - docker-compose.yml (dev), docker-compose.sitl.yml (ArduPilot SITL)
  - GitHub Actions: ci.yml (lint+pytest+docker smoke), sitl.yml (nightly)
  - tests/test_sitl_integration.py (8 tests, skip without SITL)

Phase 7 — Accuracy Validation:
  - AccuracyBenchmark + SyntheticTrajectory
  - AC-PERF-1: 80% within 50m 
  - AC-PERF-2: 60% within 20m 
  - AC-PERF-3: p95 latency < 400ms 
  - AC-PERF-4: VO drift 1km < 100m  (actual ~11m)
  - scripts/benchmark_accuracy.py CLI

Tests: 195 passed / 8 skipped

## Summary
Implemented the 15-state Error-State Kalman Filter (ESKF) from scratch using NumPy only. Covers ESKF-01 through ESKF-05.
## Key Files Created
- `src/gps_denied/schemas/eskf.py` (68 lines) — ConfidenceTier, IMUMeasurement, ESKFConfig, ESKFState schemas
- `src/gps_denied/core/eskf.py` (359 lines) — ESKF class with predict(), update_vo(), update_satellite(), get_confidence(), initialize_from_gps()
## Commits
- `57c7a6b` feat(eskf): add ESKF schema contracts (ESKF-01, ESKF-04, ESKF-05)
- `9d5337a` feat(eskf): implement 15-state ESKF core algorithm (ESKF-01..05)
## Tasks Completed
| Task | Status | Notes |
|------|--------|-------|
| Task 1: ESKF schema contracts | ✓ | All 4 classes importable |
| Task 2: ESKF core algorithm | ✓ | All acceptance criteria passed |
## Deviations
None — implemented as specified in plan.
## Self-Check: PASSED
- [x] ESKF class importable
- [x] predict() propagates state and grows covariance
- [x] update_vo() reduces position uncertainty via Kalman gain
- [x] update_satellite() corrects absolute position
- [x] get_confidence() returns correct tier
- [x] initialize_from_gps() uses CoordinateTransformer
- [x] All math NumPy only, no external filter library

## Summary
Replaced all FAKE Math stubs in CoordinateTransformer with real camera projection mathematics. Implements the complete pixel-to-GPS chain via K^-1 unprojection, camera-to-body rotation, quaternion body-to-ENU transformation, and ray-ground intersection (ESKF-06).
## Key File Modified
- `src/gps_denied/core/coordinates.py` (176 lines added) — Real K matrix math, helper functions, pixel_to_gps, gps_to_pixel, cv2.perspectiveTransform
## Commits
- `dccadd4` feat(coordinates): implement real pixel-to-GPS projection chain (ESKF-06)
## New Helpers
- `_build_intrinsic_matrix()` — K matrix from focal_length, sensor size, resolution
- `_cam_to_body_rotation()` — Rx(180deg) for nadir-pointing camera
- `_quat_to_rotation_matrix()` — Quaternion to 3x3 rotation matrix
## Deviations
None — all acceptance criteria passed.
## Self-Check: PASSED
- [x] K^-1 unprojection replaces 0.1m/pixel fake scaling
- [x] Ray-ground intersection at altitude
- [x] gps_to_pixel is exact inverse
- [x] transform_points uses cv2.perspectiveTransform
- [x] All FAKE Math stubs removed
- [x] Image center pixel projects to UAV nadir
- [x] Backward-compatible defaults (ADTI 20L V1)

# GPS-Denied Onboard
Сервіс геолокалізації знімків БПЛА в умовах відсутності GPS-сигналу.
Бортова система GPS-denied навігації для фіксованого крила БПЛА на Jetson Orin Nano Super.
Система використовує візуальну одометрію (VO), співставлення з супутниковими картами (cross-view matching) та оптимізацію траєкторії через фактор-графи для визначення координат дрона в реальному часі.
Замінює GPS-сигнал власною оцінкою позиції на основі відеопотоку (cuVSLAM), IMU та супутникових знімків. Позиція подається у польотний контролер ArduPilot у форматі `GPS_INPUT` через MAVLink при 5–10 Гц.

## Що залишилось (on-device)
1. Офлайн завантаження тайлів для зони місії → `{tile_dir}/z/x/y.png`
2. Конвертація моделей: LiteSAM/XFeat PyTorch → ONNX → TRT FP16
3. Запуск SITL: `docker compose -f docker-compose.sitl.yml up`
4. Польотні дані: записати GPS + відео → порівняти ESKF-траєкторію з ground truth
5. Калібрування: camera intrinsics + IMU noise density для конкретного апарату
