Don't automatically launch Doppler

Sending an AppleScript event to an application that's not running causes it to launch. We don't need to hold the user hostage, so a simple check for if Doppler is running has been added.

Handle diacritics on a per-character basis

This should allow for text like "fhána" to match.

Use better matcher

Automatically reconnect on disconnect

Use system-styled help button

Hide Radio from Dock

Toggle popover instead of solely present

This allows keyboard navigators to toggle between on and off.

Improve UI

Notably, Radio won't enter an infinite loop if the user closes Discord. It'll still be running, but just sending useless data (since the socket is closed).

Don't include example image in target

This causes code signing to fail, for some reason.
