data(assets): promote the four spike GLBs — first production environment assets (T-1204)

table_baroque, chair_modernist, desk_scifi (furniture, with mask
sidecars) and lion_statue (props, non-tintable) enter
client/assets/models/ under the category-first convention, byte-
identical to the spike sources (MD5-verified; spikes/ untouched,
vw_beetle excluded per the Q-067 deferral). Postprocess verified
already-applied by Blender node-graph inspection (mat_primary,
roughness=1.0/specular=0.0 shader inputs — the convenience properties
read stale defaults, the graph is authoritative), so not re-run. All
four registered in manifest.json at 'planned' with footprint_tiles
[1,1] (a flagged judgment call — normalized spike geometry erases
real-world scale; the brief ruling goes to araminta in review).
In-engine proof: clean headless import + ResourceLoader load +
instantiate for all four. Discovery documented in conventions.md §2 +
glb-gen SKILL.md: Godot externalizes the GLB's embedded texture as a
<model>_Image_0.png sidecar referenced by binary UID — it must be
committed or loading breaks with an undiscoverable dependency error.

+On first Godot import of a promoted `.glb`, the scene importer externalizes

+regenerates it deterministically. But it **must be committed alongside the

+time, and critically, **a text grep of the compiled `.scn` will not reveal
+this dependency** — the reference is a binary-encoded UID (`uid://...`), not
+a literal path string, so searching the `.scn` for the filename finds
+nothing. Losing this file costs a full debug cycle (re-copy the source `.glb`,
