Add formal enemies, remaining formal partners and synthesized UI SFX

- UI SFX v3: procedurally synthesized one-shots (Tools/synth_ui_sfx.py) wired to
  buttons, rewards, errors and red dots via UiSfx, gated by the SFX setting.
- Five formal enemies (Hornlet, Dashlet, Shellhorn, HornCaptain, GreatHorn):
  Hunyuan 50k -> 2000-tri XPbr, DGXA TokenRig, Idle/Walk/Attack, nested per type
  in PrototypeArena; PrototypeBattle.Enemy gains presentation-only Moving/Strikes.
- Formal partners for all ten pets in the arena and portraits, including new
  VineSprite, ThunderLeopard and TideWhale.
- Pipeline fixes: reject local TokenRig fallback, drop loose mesh islands,
  configurable Unity run_script timeout, companion static stage.
- Also includes concurrent work from another tool in this working tree
  (FlameLion, enemy combat FX, challenge mode, home explorer, server updates).
- Resources registered in Doc/ResDesc_*.md; verified on isolated :18081.

Image 2 is STYLE ONLY: match the FireCat companion's friendly polished chibi 3D mobile-game render, big expressive glossy eyes, appealing rounded volumes and clean readable shapes; do not copy cat features. One friendly T1 companion creature for a cozy meadow tower-defense game. Calm neutral rigging-friendly standing pose, bilaterally symmetrical, all feet grounded on a common flat plane with visible gaps between the limbs, head facing forward. Single full-body character centered, very shallow front three-quarter view (about 15 degrees off frontal), everything in frame with generous margin. Pure solid white #FFFFFF background to all corners, soft studio light, tiny contact shadow under the feet. Every part is solid and attached to the body: no floating pieces, no separate water drops, sparks, petals or particles. Simple smooth surfaces suitable for a 2000-triangle mobile model with a 1024 texture. Exactly one character; no text, no watermark, no UI, no props, no scenery, no floor base. ThunderLeopard, a small sturdy FOUR-LEGGED leopard cub standing on all four paws: soft violet-purple fur with a few darker purple rosette spots, cream muzzle and belly, round ears, big bright golden eyes, a confident playful grin. Two broad solid cyan lightning-bolt-shaped crystal plates fused onto the shoulders like small armor, and one short cyan zigzag crystal crest on the forehead; the crystals are solid attached parts with shallow seams, not floating. Medium thick tail with a cyan crystal tip, attached. Four distinct stout legs with rounded paws all grounded, level back, head held forward at rest, neck readable and separable from the shoulders for a later short head-and-shoulder pounce animation. Landscape composition showing the whole body length.",
