New Issue: [Feature Request]: fill in partial types on "show instantiation"

28194, "jabraham17", "[Feature Request]: fill in partial types on "show instantiation"", "2025-12-11T18:00:46Z"

Summary of Feature

Description:
When writing Chapel code, I might write a partial formal type spec. When using CLS, I want "show instantiation" to show me the actual type and overwrite the generic parts. Today, we just silence all type inlays when any type is given (even if that type is just ?)

Is this issue currently blocking your progress?
no

Code Sample

use List;

proc foo(x: list(?)) {
  var s = x.size;
  return s;
}
foo(new list(int));

Generic code

Show instantiation: ideally this would fill in list(/*int, false*/) (block comment is inlay)
