Subject: [PATCH] feat(dashboard): firewall UI in Black Box + alive WebGPU
 backdrop

- Black Box surfaces the memory.quarantine + episode.boundary events: a red
  "Microglial Firewall" detail panel (QUARANTINED / influenceAllowed: false +
  threat prose), hasQuarantine producer/proof-mode status, episode dividers.
  ReceiptCard renders quarantined[] + the influence badge.
- TS MemoryTraceEvent union + Receipt interface extended to mirror the Rust
  serde wire shapes exactly (memory.quarantine, episode.boundary, quarantined/
  influence_allowed/engram_phases). +13 blackbox-helpers tests.
- New lib/core: VestigeGPU (reusable raw-WebGPU boot core, 3-tier adapter
  fallback + device-loss recovery, no Three.js) and BackdropEngine, a curl-noise
  "alive purple neural field" mounted behind every route, with a Canvas2D
  fallback for pre-iOS-26 devices. SSR-safe (browser-guarded).
- ?demo=firewall loads a synthetic attack->quarantine->receipt run for offline
  launch-footage capture (real UI, synthetic data).

Verified live in preview (data-mode=webgpu, firewall panel renders), svelte-check
0 errors / 965 files.
