v1.0.0

Major Changes

• #4 69e8bce Thanks @ultrox! - Remove writeEnvFile and the exported WriteEnvFileOptions type. The library now focuses on environment validation and typed access, with no filesystem dependency or file serialization API.

  This is a breaking API change. Replace calls to envSchema.writeEnvFile(...) with envSchema.parse(source) to validate an already supplied environment. The return value remains { data, warnings }; export data as the application's typed env object. Environment loading and any file generation belong to direnv, the CI runner, or the deployment platform.

  Local development and CI use the same validation command. File-writing tests, examples, and the CI installation of direnv used by those tests have been removed.
