in some lang like rust, python

but in other lang like clang, zig
only definition of parameter highlight as variable.parameter,
reference of parameter highlight as variable.

Parameter highlights extending to references of the parameters is possible because of locals queries, for example for Rust: https://github.com/helix-editor/helix/blob/master/runtime/queries/rust/locals.scm

To support that kind of highlighting for more languages you can try writing the locals queries for those languages (in runtime/queries/zig/locals.scm for example)
