On a foreign object the pipette now reads the data channels
(metallic/smoothness/occlusion/emission) texel-exact from the material
while taking albedo from the rendered, fully-lit on-screen pixel - so the
picked colour honours baked lightmaps/ambient/SSAO while keeping the
material's PBR fidelity. Falls back to a pure screen pick when no readable
UV is available. Pull the render+readback out of PickFromScreen into a
shared TrySampleScreenColor.
The pipette now also arms on Ctrl (in addition to Shift), and Ctrl+wheel
resizes the brush; the orbit camera ignores the wheel while either modifier
is held so it does not zoom and resize at once.

hit.textureCoord is only filled for non-convex MeshColliders; on a convex
MeshCollider (or Box/Sphere/Capsule) it returns Vector2.zero, so the pick
sampled the foreign material's base map at texel (0,0) - a constant, wrong
color ("base map ignored"). Now the UV is recovered from the renderer mesh
itself (camera ray vs triangles, Moeller-Trumbore, barycentric UV) for
convex/primitive colliders, with the screen-pixel pick as fallback when the
mesh is not readable. The fast non-convex path is unchanged.

- PlayerCharacterController: latch the wall-strafe sign once at strafe
start instead of re-deriving it from the camera every frame, which
flipped at the 90-degree point while circling a cylinder and caused a
back-and-forth lock. Flat walls stay bit-identical; reset on enter/exit.
- MeshPainter.Pick: dispatch terrain hits to a splat-layer blend (full
PBR channels), terrain trees / grass / sky to rendered screen-color,
keeping texel-accurate picks for the paint mesh and foreign materials.
- Includes Unity auto-reserialization of SampleScene and three Supercyan
pack assets (URP material upgrades, skybox/lighting) from the import.

Reset the pipette toggle after a successful pick so each pick is a
one-shot action (HUD toggle follows via the Picked sync). Split the
wall-climb pose drag so the lean-out offset stays on LMB while body
rotation moves to RMB, letting both be held independently. Also pulls in
the terrain physics module and the user's scene setup for the terrain
test area.

The pipette now raycasts the nearest collider of any object, not just the
paint mesh. On a foreign hit it reads all channels texel-accurately from the
object's material maps (BaseMap/MetallicGloss/Occlusion/Emission) combined
with the material scalars per URP/Lit conventions, falling back to scalar
properties where a map is missing or the collider yields no UV. Includes
scene test props and materials for verifying foreign-object picking.

After a successful pipette pick the painter now enables all four paint
channels (albedo, metallic/smoothness, occlusion, emission) and raises a
Picked event. The HUD subscribes and re-syncs every widget (toggles,
sliders, both colour pickers) to the adopted brush values.

Pipette samples all painted channel values (albedo, metallic, smoothness,
occlusion, emission) at the clicked texel and adopts them into the brush
with every opacity forced to 1, instead of painting. The screen raycast is
extracted into a shared TryRaycastPaintMesh helper used by painting, preview
and the pipette. A pipette toggle is added to the HUD panel prefab and wired
in PaintHud.
