fix: add nil guards to prevent nil-pointer panics
- document.go: check if resp is nil before calling resp.Status() in
  Refresh(), since Playwright's Reload() can return a nil response
- archive.go: check SelectFirst() results for nil before calling
  Type() and Click(), preventing panics when DOM elements are missing

Closes #10, #11
