GameRenderer.render3dHud sets up the hand's projection at Camera's hudFov
(70, changed only by death and fluids), never the FOV option or the
sprint, speed and bow modifier. The hand pass now has its own globals
with that projection (a port of JOML setPerspective, as Projection does).
The camera harness compares the world and hand projection matrices at FOV
options 30, 70, 110 and others with vanilla's.

Camera.tick, tickFov, alignWithEntity with getMaxZoom over visual-shape
clipping, setRotation and move with JOML quaternion arithmetic,
calculateFov/calculateHudFov, getFieldOfViewModifier (now including
flight), ClientAvatarState walk/bob history (the backwards-extrapolated
walk distance and velocity-based bob) and GameRenderer.bobHurt/bobView as
the JOML pose matrix with property flags. The game renders through them,
adding hurt tilt, the camera distance and scale attributes, the mirrored
front camera and the sleeping camera. tools/test_camera_parity.py compares
18,502 cases against the real classes.
