MigrationEntry class

Ties a MigrationId to a Migration instance.

Used to register migrations with their IDs for proper ordering. The CLI generates these automatically in migrations.dart file.

Example:

final entries = [
  MigrationEntry(
    id: MigrationId.parse('m_20251130100953_create_users'),
    migration: const CreateUsersTable(),
  ),
  MigrationEntry(
    id: MigrationId.parse('m_20251130101500_add_index'),
    migration: const AddEmailIndex(),
  ),
];

// Convert to descriptors (sorted by timestamp)
final descriptors = MigrationEntry.buildDescriptors(entries);
