- Delete sqlite-adapter.ts and migrations.ts (SQLite path removed)
- Remove driver/sqlitePath from all config schemas + sec-config template
- init.ts now PG-only, no SQLite branch
- db-adapter.ts dialect narrowed to "postgres" only
- Add in-place UUIDv7 migration: detects INTEGER PKs in existing PG
databases, drops FK constraints, ALTER COLUMN TYPE to TEXT for all
15 entity tables + their FK columns, re-adds FK constraints. Idempotent
(skips if already TEXT). Existing integer IDs become string "1", "2"
etc — new inserts use proper UUIDv7 from repository.ts.
