Fix HDL and Hack Assembly syntax highlighting and queries

- Fixed HDL highlights query syntax error with #match? predicate
- Replaced #match? with #any-of? for exact string matching
- Fixed Hack Assembly outline query invalid field name
- Improved HDL syntax highlighting with comprehensive patterns
- Added HDL bracket matching for all syntax types
- Fixed XML scope mismatch from text.xml to source.xml
- Enhanced outline queries for better code navigation
