/**
 * Utilities for reading/writing `migration.ts` files.
 *
 * Rendering migration.ts source is the target's responsibility — the CLI
 * obtains source strings from a planner's `plan.renderTypeScript()`. The
 * helper here is limited to file I/O: writing the returned source with the
 * right executable bit and probing for existence.
 */
/**
 * Writes a pre-rendered `migration.ts` source string to the given package
 * directory. If the source begins with a shebang, the file is written with
 * executable permissions (0o755) so it can be run directly via
 * `./migration.ts` — the rendered scaffold ends with
 * `MigrationCLI.run(import.meta.url, M)` from
 * `@prisma-next/cli/migration-cli` (re-exported by the postgres facade),
 * which guards on the entrypoint and serializes when the file is the main
 * module.
 *
 * The source is run through prettier before writing so migration renderers
 * can produce structurally-correct but loosely-indented source and rely on
 * a single canonical format on disk. Matches what `@prisma-next/emitter`
 * already does for generated `contract.d.ts`.
