added automatic installed app detection to the adeck app which makes setting up app shortcuts much easier now since adeck can find installed apps from the pc and most of the setup happens automatically

• before this i had to find and paste exe paths manually, so i added an installed apps list to make this easier

• i kept installed apps separate from normal commands like git and npm so both dont get mixed together and the app list was getting pretty long, so i also added search to quickly find the app i want

after getting it working i tested it with different apps and also checked normal commands to make sure both still work properly
now when i select an app, its name and launch path are added to the selected key automatically
