Regex Tester & Validator

Matches a code statement terminator (`;`, `{`, or `}`) immediately followed by a newline, optional horizontal whitespace, and a `//` single-line comment. Intended for PHP/C-style languages to locate comments that appear directly after a statement without a blank line separating them, typically for enforcing comment spacing style guidelines in editors like VS Code or Sublime Text. Note the `{1}` quantifiers are redundant, and the multiline flag has no effect since no anchors are used.
