Summary

Drops Slim support from a11y-lint. The gem now targets ERB and Phlex only.

Breaking change. .slim files are no longer discovered or linted. SlimRunner, SlimNode, and SlimLoadError are removed, along with the slim development dependency.

Removed

• lib/a11y/lint/slim_runner.rb and lib/a11y/lint/slim_node.rb
• All Slim test files (14), including the six unsuffixed perceivable rule tests that were Slim-only
• The Slim dummy app fixture (home.html.slim)
• slim from the gemspec and lockfile

Changed

• CLI globs only .erb and .rb; .rb routes to PhlexRunner, everything else to ErbRunner. The "no files found" message now reads "No .erb or .rb files found"
• CLI, configuration, and offense tests converted from Slim to ERB fixtures; the mixed-pipeline CLI test now covers ERB + Phlex
• CHANGELOG entry under Unreleased
• README, CLAUDE.md, .claude/rules/testing.md, and the implement/task commands no longer reference Slim; the testing rule's calling-style examples are now ERB
• Docs site: Shared::CodeTabs drops its Slim tab and kwarg; rule pages lose their Slim samples and "Slim equivalent" sections; CONTRIBUTING updated

Test plan

• bundle exec rake — 570 runs, 985 assertions, 0 failures; RuboCop clean
• bundle exec a11y-lint test/fixtures/dummy_app — 38 offenses across ERB and Phlex fixtures, unchanged
• A directory containing only a .slim file reports "No .erb or .rb files found"
• Docs site build (cd docs && bin/bridgetown build) — not run locally; the component change is a one-tab removal
