Subject: [PATCH] Reduce release package size

The current release package contains files that are not required at runtime,
such as `.github`, `docs`, and `examples`.

```ruby
Dir.chdir(File.expand_path("..", __FILE__)) do
  %x(git ls-files -z).split("\x0").reject { |f| f.match(%r{^(test|spec|features)/}) }
end
=>
[".gitattributes",
 ".github/dependabot.yml",
 ".github/workflows/ci.yml",
 ".github/workflows/release.yml",
 ".gitignore",
 ".rubocop.yml",
 "AGENTS.md",
 "CHANGELOG.md",
 "CODE_OF_CONDUCT.md",
 "Gemfile",
 "LICENSE",
(snip)
```

This PR removes unnecessary files where possible to reduce the size of the release package.
