Description of the new feature / enhancement

I have two features that I used a lot in PowerToys Run that don't work the same in CmdPal:

1. Show environment variables in file search results
2. Ability to enter tool shortcut after you've started typing

Scenario when this would be used?

Show environment variables in file search results:

PowerToys Run Behaviour:

1. Attempting to open %userprofile%
2. Type %user in CmdPal
3. %userprofile% is the top result, press enter to open the folder

CmdPal Behaviour:

Currently, you have to type out the entire %userprofile% in order for this to display in CmdPal, and even then it's the second option.

Second request that was a dupe of #38877

Ability to enter tool shortcut after you've started typing

PowerToys Run Behaviour:

1. Type display in the search box
2. Realise you only wanted to search in settings
3. Navigate back to the start of the line and type $
4. Only results from settings are displayed

CmdPal Behaviour:

After adding the $ at the start of the search query, only web and file fallback results are displayed
