Fixes #1026.

The CSS-class tutorial's greedy expression consumes the rest of the line, so two links on one line receive a class only on the first link. It can also match article or abbr when the configured tag is a.

Match only the opening tag name with a whitespace-or-> boundary, and insert the class immediately after it. Attributes remain untouched, including quoted > characters and attributes on multiple lines. Add a short explanation to the tutorial.

Five regression checks execute the bindings extracted from the documented snippet through the actual converter: repeated links, tag-name prefixes, quoted angle brackets, multiline attributes, and the tutorial's list classes. All five fail before the change (the list case differs only in redundant whitespace) and pass afterward.

Validation: npm test passes all 3,179 tests across 26 files; ESLint reports no errors and one existing unused-variable warning in decodeEntities.js. git diff --check passes. Based on develop as requested by CONTRIBUTING.md. No library runtime code or dependencies changed; no browser matrix was run for this documentation example.
