📝 WalkthroughWalkthroughThe semantic token provider expands highlighting across ZModel declarations and expressions. It adds classifications for procedures, parameters, literals, operators, enums, predicate bindings, mutations, references, decorators, and regular expression arguments. ChangesSemantic highlighting
Estimated code review effort: 2 (Simple) | ~15 minutes Merge Risk:⚪ Minimal · up to The change improves semantic highlighting across several syntax elements; one parameter form may remain unhighlighted, causing a limited editor-coloring inconsistency. No actionable merge-blocking risk remains, and the PR is merge-ready after normal checks. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Fixes many semantic highlighting issues, including number literals, enums, enum members, boolean literals, null literals, binary operators, unary operators, attribute args, function args, function return types, regex patterns, procedure args, and procedure return types.
Differences may or may not be seen depending on the user's theme.
There are two options. Option 1 is identical to Prisma with the exception of enum members, which are now highlighted differently from fields.
Before
After (Option 1, virtually identical to Prisma)
After (Option 2, more varied colors)
