feat(neuroruntime): wire Microglial Firewall into the write path

Add the firewall causal slice so a poisoned/injected memory is screened,
quarantined, and proven held-out on the receipt (influence_allowed=false):

- screen_write() detector (neuroscience/microglial_firewall.rs): deterministic
  prompt-injection / exfiltration / poisoning screen with NFKC + homoglyph
  folding and word-boundary matching to avoid false quarantines.
- Receipt gains quarantined[] / influence_allowed / engram_phases (additive,
  serde-default, back-compatible with old receipts).
- New trace events memory.quarantine + episode.boundary (mirror the TS union).
- gate_writes() now screens every write and, on a quarantine verdict, suppresses
  the node (held out of retrieval) + records the quarantine receipt + events, so
  influence_allowed=false is ENFORCED, not cosmetic. Content capped at 16KB.
- VestigeEvent::MemoryQuarantined live broadcast.

Verified: cargo test vestige-core/vestige-mcp green, clippy -D warnings clean,
integration test proves a screened injection is absent from the write's retrieval.
