Symbol navigation with `workspace.library` does not take effect

[yeshan333]

Reproduce Project: https://github.com/yeshan333/luacheck_sarif_report_demo/tree/sarif-report-pr

Configuration:
I've configured .luarc.json to reference external symbol definitions:

{
  "$schema": "https://raw.githubusercontent.com/EmmyLuaLs/emmylua-analyzer-rust/refs/heads/main/crates/emmylua_code_analysis/resources/schema.json",
  "workspace.library": [
     "$HOME/.luals/addon"
  ],
  "encoding": "utf-8",
  "enableReindex": true
}

External Libraries:
The ~/.luals/addon directory contains two third-party LuaCATS libraries from https://github.com/LuaCATS:

$ ls -al ~/.luals/addon
total 0
drwxr-xr-x@ 4 yeshan333  staff  128 Sep 13 15:16 ./
drwxr-xr-x@ 3 yeshan333  staff   96 Sep 13 01:35 ../
drwxr-xr-x@ 5 yeshan333  staff  160 Sep 13 15:16 busted/
drwxr-xr-x@ 5 yeshan333  staff  160 Sep 13 14:32 luassert/

Problem:
Symbol navigation for luassert within describe blocks is not functioning when using emmylua-analyzer-rust.

Verification:
When switching to lua-language-server, symbol navigation works correctly with the following VS Code configuration:

"Lua.workspace.library": [
    "$HOME/.luals/addon"
]

assert is not a global variable
