- filterChildShellEnv now also filters Bun-autoloaded .env.{NODE_ENV||development}
entries, closing the .env.production/.env.development leak into child shells.
- parseEnvLine skips backslash-escaped quotes when locating the closing
delimiter, restoring baseline/Bun-literal handling of values like JSON="{\"a\":1}"
that the new parser truncated.
- Adds a parseEnvFile regression test for escaped quotes.
