chore(assets): Synty intake spike — scripts, evidence logs, verdict data (T-1089)

Bridge-C evidence spike: unitypackage extraction, rest-pose recon, garment transplant onto the Quaternius rig (Data Transfer POLYINTERP_NEAREST), 11-body batch fit, Godot QA scenes. Technical PASS; route nonetheless REJECTED by product call (cost, baked body-segment modularity, style) — full trail on T-1089. Salvage: source-agnostic transplant/batch-fit scripts (the G1-family pipeline for any donor mesh) and the T-1090 discovery (5 body types misrender bare). Extracted vendor payload (spikes/**/raw/) now gitignored. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
