Walkthrough

This pull request introduces a patch release for marko-vscode that refines syntax highlighting behavior. A changeset entry is added to document the release. The marko.tmLanguage.json TextMate grammar file is updated with 22 lines of changes that incorporate negative lookahead assertions (e.g., (?![a-zA-Z0-9_$@-])) into various begin patterns. These patterns govern when embedded blocks for constructs like HTML comments, style tags, script tags, and void elements are recognized. The modifications reduce false positives by ensuring these patterns do not match when followed by alphanumeric characters or specific symbols, addressing edge cases around tag name boundaries.
