/**
 * Standalone TypeORM CLI DataSource for the MAIN connection (auth + audit).
 *
 * The app runs the main connection as a separate, ALWAYS-SQLite connection (app.module.ts), distinct
 * from the pluggable data connection. The default data-source.ts CLI only manages the data
 * connection's migrations, so without this the CLI could not run/generate the main-owned migrations
 * (migrations-main) — which matters the moment boot auto-migration is turned off
 * (MAIN_DATABASE_SYNCHRONIZE=false), where the schema must be managed via the CLI instead.
 *
 * Mirrors the runtime main connection exactly: SQLite at ./data/main.sqlite, auth/audit entities,
 * migrations-main. synchronize is always false here — the CLI manages schema via migrations.
 *
 * Usage: `npm run migration:run:main` (dev) / `migration:run:main:prod` (compiled).
