feat: add Perl language rules and update documentation

Add rules/perl/ with 5 rule files (coding-style, testing, patterns,
  hooks, security) following the same structure as existing languages.
  Update README.md, README.zh-CN.md, and rules/README.md to document
  Perl support including badges, directory trees, install instructions,
  and rule counts.
