Research direction

Start by locating the lexer for @PCode tags and reading how it currently balances braces; then inspect the pcode lexer to understand how it identifies actual brace tokens. Done means a } inside a string no longer ends the tag, while real brace tokens still determine its boundary. The issue names no files or tests.

Written by the indexing model from the issue text.

Description

Reproduction:

@PCode {
    Push "}"
}

The lexing of @PCode tags is too simple, and just looks for an unbalanced amount of } compared {. We should probably use the pcode lexer and count actual {/} tokens, instead.
