docs(vault): audit tranche 1 — one-owner dedupe of the observability cluster, dead-shape numbers destroyed

Purpose-test pass over the audit findings (every verdict re-verified
against the file before touching it; three scout findings were hallucinated
— a nonexistent filename, my own changelog line, and sanctioned Eras rows):

- Observability Provisioning: destroyed the 63-line 'Current delivered
  state' block — chain topology/relay/delivery restates [[Observability]]
  and [[Alertmanager]] (those are the owners). Its three sole-custody laws
  MOVED to Stale Signal Audit as 'Three rules that outlive the incident':
  down-beside-healthy -> read lastError; Prometheus alert state in process
  vs Alertmanager's --storage.path persistence; candidate-arm metrics are
  never fleet state.
- RDNA4 MoE VRAM budget: kept the laws (registry over-prices the pool;
  never reuse a B/token ratio across geometries; pin pool bytes
  floor-sized), era-labelled the rates, destroyed the measured ladder
  table for the superseded shape-G/bf16 rungs.
- Stale Signal Audit: new rules section + Provisioning Related link.
