sqlite persistence: the store moves from db.json to dist.db (P5.2)

Browse Source 
src/repo/db.sx persists the whole Repo to <store>/dist.db through the
vendored SQLite bindings, keeping the load-whole/save-whole call shape.
One table per entity; enums as lowercase variant names; list order
round-trips via rowid. Enforced uniqueness: apps.slug,
channels(app_id, name), tokens.token_hash; lookup indexes on
releases(app_id) and artifacts(sha256) (non-unique - identical bytes
may ship in several releases). save is DELETE-all + INSERT-all inside
BEGIN IMMEDIATE...COMMIT with rollback on failure; every connection
sets busy_timeout so the CLI and a running distd interleave safely.

A store holding only a pre-SQLite db.json imports once on first load,
then the file is renamed db.json.imported; a store with neither starts
empty. Consumers gate on db.store_exists instead of probing db.json.
The JSON read-back stays for the import path; the entity->json writers
stay for distd's /api responses.

Tests that parsed db.json directly now assert by querying dist.db
through the SQLite bindings; tests/db_import.sx pins the import path;
tests/repo_roundtrip.sx pins the SQLite round-trip. make test 22/22.
