fix: apply gofmt formatting and stabilize doc comments

- Align struct field in platform_security_test.go (gofmt)
- Rewrite two doc comments in shell.go to avoid the single-quote
  sequence that gofmt's doc comment formatter converts to a Unicode
  right double quotation mark (U+201D), breaking CI gofmt checks
