…escription (#8849)

The CameraFrame script fails to parse in the Editor after the dual-LUT
change (#8749). The texture2 attribute description contained an inline
JSDoc {@link ColorLUT#blend} tag.

When a JSDoc summary contains {@link}, TypeScript represents the comment
as a NodeArray of comment nodes rather than a plain string. The attribute
parser stores this verbatim as the attribute description, and because
those nodes carry circular parent references, serializing the parsed
schema throws 'Converting circular structure to JSON' - surfacing as an
Editor parse error even though the program itself parses without error.

Replace the inline link with plain prose so the description stays a
string and the schema serializes cleanly.

…es (#8850)

XrNavigation reads thumbstick input from gamepad.axes[2]/[3] (the WebXR
xr-standard mapping). Apple Vision Pro hand-tracking input sources expose a
gamepad with an empty axes array, so those reads return undefined and
-undefined is NaN. The smooth-turn guard 'Math.abs(turn) <= threshold' does
not catch NaN (NaN comparisons are always false), so the NaN flowed into
rotateLocal and corrupted the camera rig transform to NaN permanently. Splats
still submitted but projected to NaN, leaving the scene blank in VR on AVP
while head tracking worked. Controller headsets (Quest) report real axes and
were unaffected.

Skip input sources whose gamepad does not expose thumbstick axes
(axes.length < 4) in handleSmoothLocomotion and handleSnapVertical.

…BLE (#8856)

Materials sampling scene depth via screenDepthPS decoded it in the wrong
format on textureFloatRenderable devices. The prepass allocates the linear
depth texture as R32F when device.textureFloatRenderable (packed RGBA8
otherwise), but the chunk's decode was gated by a separate SCENE_DEPTHMAP_FLOAT
define that the material path never set.

Select the decode in the chunk from the global CAPS_TEXTURE_FLOAT_RENDERABLE
define instead, so the texture format and the shader decode share a single
source of truth. Removes SCENE_DEPTHMAP_FLOAT and the device branch (and unused
device param) from addScreenDepthChunkDefines, and updates its four callers.

* #8833 fix: ensure dof effect is resolution independent

* Update src/extras/render-passes/frame-pass-dof.js

* Update src/extras/render-passes/render-pass-dof-blur.js

* fix: remove duplicate invReferenceHeight declaration

A suggestion was applied one line off, leaving the original
invReferenceHeight declaration in place alongside the guarded one,
breaking the build. Remove the duplicate and keep the reference-height
guard.
