/**
 * Minimal `.env` file parser used by the CLI for `validate` / `check`.
 *
 * Supports the common subset of dotenv syntax:
 *   - `KEY=value`
 *   - Surrounding double or single quotes (stripped)
 *   - Lines starting with `#` are comments
 *   - Inline `#` comments after an unquoted value
 *   - Blank lines ignored
 *
 * Anything more exotic (variable expansion, multi-line values) is
 * deliberately out of scope. Use dotenv-expand etc. before piping the
 * result into `loadSettings(...)` if you need it.
