Split one-class-per-file todos

[MikeMcQuaid]

• Removes inline Style/OneClassPerFile todos by giving each affected top-level class or module its own file.
• Keeps existing entry-point requires so callers retain stable load paths while RuboCop can enforce the style.

Pull request overview

This PR removes Style/OneClassPerFile RuboCop todos by extracting previously co-located top-level classes/modules into dedicated files, while keeping existing entry-point requires to preserve stable load paths across Homebrew.

Changes:

• Split several top-level classes/modules out of “entry-point” files (e.g., tap.rb, tab.rb, resource.rb, options.rb, lock_file.rb, etc.) and replaced inline definitions with require statements.
• Moved the download strategy class hierarchy into individual files under Library/Homebrew/download_strategy/.
• Split various core extensions (blank?/deep_dup/duplicable/enumerable) into one-class-per-file layouts and added corresponding requires.
