Patch

Informational dotenv-style patch. Review before applying; masked values are intentionally not reusable.

Parser and privacy: Supports blank lines, comments, optional export, unquoted values, and single/double quoted values with common double-quote escapes. Variable expansion and multiline quoted values are intentionally unsupported. Duplicate keys are reported and the final assignment wins. Processing is memory-only; there is no network request or persistence.
