Extract the AES-256-GCM Bytes codec from persistence into a shared bytes-codec module so the conversation summary and the new personal-fact store reuse one ArrayBuffer-backed implementation. Add the CoachFact table (migration 0116) for durable, user-scoped facts the Coach extracts from conversations — encrypted fact text, plain category/confidence/ source for rank-without-decrypt, soft-delete for a reversible forget.

-- Additive, multi-tenant-safe: one new table + index + FK, no column on an

-- existing hot table, no backfill. The fact text is encrypted at rest

-- (AES-256-GCM, same codec as coach_messages.encrypted_content); category /

-- confidence / source stay plain so the injection picker can rank without a

-- per-row decrypt. Soft-delete via deleted_at keeps "forget this" auditable.
