Enable rubocop on all files, with exceptions

[jamis]

Previously, we have opted most of the files out of the linter with # rubocop:todo all at the top of most of them. This PR removes that line and instead adds exceptions to a new .rubocop_todo.yml file. This PR also applies (via rubocop -a) standard string quoting and most other safely "autocorrectable" cops.

[Copilot]

Pull request overview

This PR enables RuboCop across the codebase by removing per-file # rubocop:todo all opt-outs and centralizing lint exceptions in .rubocop_todo.yml, while also applying RuboCop autocorrections (quoting, formatting, small refactors) and adding a Rake task to run RuboCop.

Changes:

• Remove widespread # rubocop:todo all file-level opt-outs and rely on .rubocop_todo.yml via .rubocop.yml.
• Apply safe autocorrections across lib/, examples/, gemfiles/ and related files.
• Add rake rubocop task + optional Git hook installer in Rakefile.
