feat: Implement twig cli command to launch twig from cli

[ReeceJones]

My workflow revolves around the CLI, and I launch all of my tools from the command line. Imagine my shock when I couldn't do the same with Twig!

This PR adds functionality to install and uninstall a twig cli that is used to launch the Twig electron application.

Talked to Reece on Slack about this, love it, 2s thought here: how does cursor handle the relationship between their vscode fork and the cursor cli command? if I uninstall the fork does it clean up the CLI command properly? Someone should do a sanity check on how they've done it before we merge this so we make sure there's a binding relationship with the desktop app.
