Memory V1: remembered facts, your instructions, one screen

Coworkers remember durable things you tell them and use them in future sessions.
One Settings screen lists everything remembered - edit, delete, or stop new saves; standing instructions ride along.
Knowledge is session-stable, the save switch is per-message; sqlite gains a summary column via in-place migration.
