[Feature] [nimsuggest] semantik `highlight` for unused imports and dead code

[aMOPel]

Summary

Feature Request

Semantik tokens for

• unused imports
• dead code sections

after a highlight request to nimsuggest.

This would allow the LSP the give semantic tokens to the editor and the editor to then highlight those sections as comments or similar, which would improve the developer experience.

Description

Since chk does already know about these things, it shouldn't be too complicated to give the same information to highlight.

Examples

import std/strutils # unused import

if true:
  echo "hi"
else: 
  echo "hi" # dead code # not detected by nimsuggest chk yet

for i in 0..5:
  echo "hi"
  break
  echo "hi" # dead code

proc a() =
  echo "hi"
  return
  echo "hi" # dead code
