D1 migrations support nested layouts via migrations_pattern

You can now point wrangler d1 migrations apply at a nested migrations layout — such as the one produced by Drizzle ↗ (migrations/0001_init/migration.sql) — using the new migrations_pattern D1 binding config:

{
	"d1_databases": [
		{
			"binding": "DB",
			"database_name": "my-database",
			"database_id": "<UUID>",
			"migrations_dir": "migrations",
			"migrations_pattern": "migrations/*/migration.sql",
		},
	],
}

migrations_pattern is a glob (relative to your Wrangler config file) used to discover migration files. It defaults to ${migrations_dir}/*.sql, so existing projects keep working unchanged. Each migration's name is recorded in the migrations table as a path relative to migrations_dir.
