Jason Tudisco 2e1a0ac858 feat: add SHA-256 integrity hashes to messages with copy/link buttons

Add a hash column to messages table computed from SHA-256(created_at + content)
to ensure message integrity. Existing messages get backfilled during migration.
All messages now show copy and permalink buttons on hover, with hash-based
URL fragments that auto-scroll and highlight the target message.
