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

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?

Reproduce the issue with useNerdFont=true in ~/.config/inshellisense/rc.toml and a PowerShell or cmd session, using the commands and glyph checks described above. Read runtime.ts runCommand() and suggestions.ts getIcon(), then compare them with the supported commands in suggestions.ts NerdFontIcons. Done means top-level commands such as git and node display their Nerd Font glyphs.
