We Are Forking dotenvy into dotenv-ng

The SecretSpec team has released dotenv-ng 1.0, a Rust implementation for loading and rendering .env files, forked from dotenvy after a parser bug corrupted secrets containing dollar signs. The fork addresses dotenvy's maintenance gap and adds improvements like literal dollar signs by default, a source-aware parser, and validation before environment mutation. dotenv-ng is now used in SecretSpec 0.20.
