"""
Universal Persistence Layer

SQLite-backed persistence for features that need project-scoped state:
memos, search index, codebook, cases, queries, smart codes.

A single `<task_dir>/project.sqlite` file holds all tables. Modules register
their schemas via the migration registry; on each `get_db()` call any pending
migrations run inside a transaction.

This package is universal — not gated to QDA Mode. Both standard annotation
projects and QDA Mode projects can read/write to the same DB; QDA Mode just
populates more tables.
