fix(test): restore full test suite on Windows

- Strip both slash and backslash trailing separators in resolveBundleDir

- Add cross-platform npm helper for subprocess/snapshot builds

- Set USERPROFILE alongside HOME in subprocess tests

- Replace Unix-only rm with unlinkSync for credential cleanup

- Skip symlink and chmod assertions when platform cannot honor them

- Normalize CRLF in frontmatter description parsing

- Enforce LF line endings via .gitattributes
