feat(showcase): add hover-bike (vehicles)

The second piece in the vehicles category: a sci-fi hover bike parked on
its landing skids. A sculpted fuselage lofted from superellipse sections
(teal livery with twin pearl stripes over a shoulder parting line, dark
composite belly, parting groove and three panel seams, a tank hump and a
tail cowl) runs as a neck into each of two ducted fans 1.60 m apart.
Intake grilles, tail vents, a crown vent and gunmetal cooling fins sit on
the closed-form surface along its normal. A stitched, pleated saddle is
draped over the crown. Cockpit: a riser in a pleated boot, top clamp,
clip-on bars with ribbed grips, bar-end weights, lever perches and levers,
an instrument cluster with an emissive screen, a smoked flyscreen and a
headlight pod (housing, lamp, glass lens). Two exhaust nozzles with
glowing cores leave the tail over the rear fan. Each fan: an airfoil-
section shroud with an accent band and a marker light, a motor can on
four canted stator vanes, a rotor hub, spinner and seven twisted, lofted
blades wrapped onto their own cylinders (the rotors are handed). Booms
with flanges, cross tubes and foot pegs; two skids on four struts. Nine
materials: livery, composite, gunmetal, rubber, leather, light, glass,
anodised, carbon.

Blender: E:\Blender-Developer-Tools\.scratch\5.2\blender-5.2.1-windows-x64\blender.exe
reports "Blender 5.2.1 LTS". 4.5 LTS and 5.1 are left to CI (not run locally).

Recomputed budgets (5.2.1):
- 44500 tris (band 43700-45300); LOD1 0.5000, LOD2 0.2200
- 9 materials: livery 3598, composite 5924, gunmetal 3970, rubber 1500,
  leather 2428, light 636, glass 656, anodised 3840, carbon 1484 faces
- UVs in 0..1, overlap 0; AABB 2.2355 x 0.6598 x 1.0556 m, zmin 0
- collider 2172 tris (ceiling 2280); bake FINISHED; glTF 3392404 B
- hygiene all 0, zero coplanar cross-shell pairs (the handlebar halves
  start 20 mm either side of the centreline so their end caps do not share
  the y = 0 plane)
- both skids' lowest vertices at 0.00000
- fans: hubs and cans 0.001 mm off the shroud axes, shrouds level, pitch
  1.60000 m; tip clearance 9.8 mm both fans (band 6-14 mm, ray from the
  axis to the inner wall); 7 + 7 blades, worst gap error 0.0001 deg
- fuselage mirror deviation 0.000 mm (eps 0.5), 1.0330 x 0.3440 m, saddle
  top 0.8522 m
- mass centre 0.2599 m inside the skids' contact polygon (149.4 kg, floor
  0.200); one connected assembly, 102 shells
- two default runs print identical measurements

Falsifiers (flag -> measured -> exit):
- --skip-decimate -> LOD1 ratio 1.0000 -> 9
- --stray-vert -> loose_v 1 -> 15
- --lift-z -> zmin 0.05000 -> 16
- --float-skid -> left skid zmin 0.00400 -> 16
- --offset-hub -> rear rotor 0.00250 m off the shroud axis -> 17
- --long-blades -> rear tip clearance -0.0022 m -> 18
- --odd-hull -> mirror deviation 0.00800 m -> 19
- --skew-blade -> worst gap error 4.000 deg -> 20
- --narrow-skids -> stance margin 0.1499 m -> 21
- --pop-lens -> 2 components -> 22
Envelope and tris unchanged under every falsifier; every earlier budget
green. --offset-hub first also moved the blade gaps 0.80 deg (spacing was
read about the shroud axis); spacing is now read about the rotor's own
hub, and the shifted rotor fails coaxiality alone (clearance 7.3 mm, in
band).

Render: render_hero.py wrote hero and preview. Framing fill x 0.737,
y 0.850, margins >= 0.028. Asset-quality floors pass (edge90 0.046); a
violation remaps to exit 23.

Asset sheet (docs/gallery/asset-sheets/hover-bike.webp): not the least-
designed object in the lineup; the hydrant is plainer. It reads at once
as a hover bike: saddle, bars, two ducted fans with spinners and blades,
nozzles, skids. Weak points: the skids and booms are plain tubes, and the
riser and clamp are blocky next to the fuselage.

Contact sheet: luma 0.2408 against calibration 0.2369-0.2428 (in band).
Stage 0.2180 against 0.1919-0.2517 (in band). Wedge warmth -0.0772
against -0.1440/+0.1052/+0.0921 (inside the spread; the brightest lower-
half pixels are teal shroud highlights, the wall pool itself is warm).
Saturation 0.2387 against 0.1525-0.2367 (slightly above: teal livery).
Thumbnail legibility good. The first draft measured luma 0.268; relit by
lowering the key, fill and wedge.

Also updated: README, CLAUDE.md and ROADMAP counts and entries, the
asset_sheet.py SELECT row, catalog.json, plugin.json and the regenerated
gallery. build_gallery, check_site_links (99 pages, 0 failures),
check_falsifier_targets, check_exit_code_readme, check_engine_id and
check_gallery_images all pass.

 The content is consumed by AI coding agents reading these files directly from a checkout — **there is no MCP server in this repository, and none is required**. Cursor applies `rules/*.mdc` automatically wherever their scope globs match and takes skills by name in chat; Claude Code reads `skills/` and `rules/` from the project workspace, or from this repo kept as a referenced checkout. Any agent that can read files in a workspace can use it the same way. There is no build step for the content — edit the Markdown and Python files directly.
