Fix CI: rubocop, cspell, and stale test mocks

- Wrap escape_glob_metacharacters in `class << self` to satisfy
  Style/ClassMethodsDefinitions
- Add `metacharacters` and `Bslug` to project-words for cspell
- Update Dir.glob mocks in resolve_test_commands_test to return
  paths relative to `base:`, matching the new test_style.rb contract
