Fix 001_init.js to follow proper migration pattern

- Changed from standalone script to proper migration with exports.up/down
- Removed process.exit() calls that were terminating the migration runner
- Removed immediate execution of runMigrations()
- Now properly exports migration functions like other migrations

This was the root cause - 001_init.js was executing immediately when
required and calling process.exit(), preventing it from being run as
a migration and causing 029 to run first on an empty database.
