- sh: reject CR/LF in archive entry names before the literal `..` glob so
a `..\r` entry cannot bypass path validation.
- bat: prefer Tls12+Tls13 in PowerShell helpers, fall back to Tls12 alone
on older .NET Framework where the Tls13 enum is missing.
- bat: document the implicit `:ValidateOptions` dependency next to the
qwen.cmd wrapper writer so loosening the validator stays a conscious
choice.
- build-standalone-release: surface the `xz-utils` host requirement for
Linux Node downloads in `--help`.
- release-script-utils: support `--key=value` form in `parseCliArgs`.
- tests: cover the new CRLF message, TLS string, and `--key=value` parsing;
register process-level signal/exit handlers in `ensureMinimalDist` so a
crashed test still restores `dist/`.
