Add camera calibration toolchain and armor pose solver

- capture_calib: capture calibration images (MindVision / USB) with a live
  quality gate (Laplacian sharpness, 3x3 coverage, board auto-detect)
- calibrate: batch intrinsics from calib_images/, writes configs/camera.yaml
- camera_calib: CameraCalib loader (intrinsics + distortion, cached
  undistort remap) and solvePose() via IPPE with a reprojection gate
- configs/camera.yaml: MV-SUA131GC intrinsics, RMS 0.483 px over 31 images,
  ruler-verified distance error < 2%
- xmake: three targets sharing an rm_deps rule, C++17
- gitignore: keep calibration photos/videos and generated
  compile_commands.json out of the repo
