Export memory digest to agent hosts

[ScriptedAlchemy]

Summary

• Add a trust-ranked, bounded memory digest exporter that snapshots approved durable facts and projects them into agent host prompt channels.
• Wire digest refreshes after fact proposal and memory curation applies, and export via managed-skill install paths for supported hosts while keeping Codex shareable plugin bundles memory-free.
• Add the automation.export_memory_digest config gate across CLI/dashboard surfaces and coverage for rendering, gating, overlay refresh, and config round-trips.
