Nerd Font glyphs not used (for top-level commands)

[Daniel-Moench]

Describe the bug
With a Nerd Font setup (#350), the glyphs are not actually used (on the top level command).

To Reproduce

• Install a nerd font and setup your terminal to use it. (for me "FiraCode Nerd Font Mono" in Windows Terminal @ Windows 11)
• set useNerdFont=true in ~/.config/inshellisense/rc.toml
• start a new session (for me is -s pwsh or cmd)
  • ensure glyphs are actually rendered, e.g.

  Write-Host "`u{E702} git  `u{E7B0} docker  `u{E709} github  `u{ED0D} node"

  should look like:
  
• type "git" or "node" or any ot the supported commands listed in suggestions.tx NerdFontIcons
• result, no glyphs:

Expected behavior
Glyphs should be shown (for top-level commands)

Environment

• OS: Win 11
• Output of is --version: 0.0.2
• Nodejs Version: 26.5.1
• Shell: pwsh, cmd
• Shell Version: 7.6.4

Additional context
I did a quick lookup and found that runtime.ts runCommand() resolves hard coded icons for aliases and specs. This may or may not explain the issue.
Thus, I suppose suggestions.ts getIcon() may not be called on the top-level, so the main purpose of the glyphs is basically never achieved?
