STATE-WP-0093: per-recipient broadcast receipts and standing notices (T01-T06).

Founder approved T01 on 2026-09-22 (D2, D3, D6 as recommended).
- T02: message_receipts table; kind/expires_at/supersedes_id on
  agent_messages; migration d7e8f9a0b1c2 archives existing broadcasts,
  leaves direct messages untouched, reversible.
- T03: reader-aware mark-read (unattributed broadcast mark-read is a
  metered, deprecated no-op), delivery receipts on the scoped unread inbox,
  POST /messages/{id}/ack, news/standing kinds, expiry, supersede, broadcast
  archive no longer stamps read_at, reply writes the replier's receipt.
- T04 (state-hub part): Codex MCP reader param and acknowledge_notice;
  hub-core part handed off (message 69fc387c).
- T05: GET /messages/notices, standing_notices in /state/summary,
  dashboard standing-notices panel.
- T06: 17 new tests; full suite green.
