johba e503273fba feat: vault — publishing gate for external-facing agent actions (#19)
Implements the vault subsystem: a JSONL queue and gate agent that sits
between agent output and irreversible external actions (emails, posts,
API calls, charges).

New files:
- vault/vault-poll.sh: cron entry (*/30), three phases: retry approved,
  timeout escalations (48h), invoke vault-agent for new pending actions
- vault/vault-agent.sh: claude -p wrapper that classifies and routes
  actions based on risk × reversibility routing table
- vault/vault-fire.sh: two-phase dispatcher (pending→approved→fired)
  with per-action locking and webhook-call handler
- vault/vault-reject.sh: moves actions to rejected/ with reason + timestamp
- vault/PROMPT.md: vault-agent system prompt with routing table

Modified:
- lib/matrix_listener.sh: new vault dispatch branch for APPROVE/REJECT
  replies to escalation threads
