fix(examples): redesign damped-track-aim as a ring of spotlights aimed at a glowing orb

The spike cage bled past three edges, blew out its core and showed a stray
plinth crescent. The subject is now twelve lathed spotlight heads: red enamel
cans with brass bezels, steel cooling fins, tilt-lock knobs and warm lenses on
local +Z. They stand on steel stands with ball pivots at alternating low and
high heights, in an open ring around an amber orb on a turned brass pedestal.
Every head is created with an identity rotation, so DAMPED_TRACK alone swings
each lens onto the orb: heads above it aim down, heads below aim up. The ring
opens toward the camera so no head hides the orb.

The check logic is unchanged (renamed Needle/Core -> Lamp/Orb). The render path
now runs the gallery_framing gate (exit 10). The old Framing deviation is gone,
since the composition sits inside the Layer 1 band. The no-file exit moves from
10 to 12. The view transform moves from Filmic to Standard per VISUAL-STYLE.

Evidence (live runs, local):
- .scratch/blender-5.2.1-windows-x64/blender.exe (Blender 5.2.1 LTS):
  check-only exit 0, "12 DAMPED_TRACK lamp heads -> Orb on TRACK_Z; worst aim
  dot=1.000000". --mute exits 7 ("Lamp_00 mute=True influence=1.0").
  Aim-dot probe (scratch copy reading the lens axis as -Z, deleted after)
  exits 9: "aim dot=-1.000000 (179.97 deg) < 0.998".
- .scratch/blender-4.5.11-windows-x64/blender.exe (Blender 4.5.11 LTS):
  check-only exit 0, same output. The render path ran on 5.2.1 only.
- Framing: fill x=0.712 y=0.756, margins l=0.144 r=0.144 b=0.128 t=0.117.
- Contact sheet (docs/gallery/contact-sheets/damped-track-aim-contact-sheet.webp):
  candidate luma 0.237 / stage 0.218 / warmth +0.105 / sat 0.178, against
  armature-bend 0.279/0.213/-0.428/0.144 (pre-redesign hero at this base)
  and bmesh-gear 0.236/0.177/+0.303/0.250. Luma matches bmesh-gear. The stage
  is slightly brighter because of the warm wedge pool on the upper-right
  wall. Warmth and saturation sit inside the set's range.

 `Object.constraints.new('DAMPED_TRACK')` — the data-API path, not
 `bpy.ops.object.constraint_add` (which needs an active object and fails in
 headless loops). Damped Track is the twist-stable aim constraint: it points one
 local axis at a target without the roll fights Track To is known for.
