Deep linking functionality for one-click server adding

[CakeLancelot]

I think that having a way to prompt the user to add a server from a link could be a really nice QOL improvement. Similar to how Steam can open store pages or launch a game just by providing a steam:// URL.

Examples:

• openfusion://addserver/endpoint/api.dexlabs.systems
• openfusion://addserver/simple/127.0.0.1%3A23000%3Fversion%3Dec8063b2-54d4-4ee1-8d9e-381f5babd420
  • (decodes to openfusion://addserver/simple/127.0.0.1:23000?version=ec8063b2-54d4-4ee1-8d9e-381f5babd420)

Once these links are opened in the launcher, we can prefill the data provided in the deep link, while allowing the user to pick the data that wasn't provided (e.g. server name). The only pain point I can think of right now is that we will really need to scrutinize the code to make sure there wouldn't be any vulnerabilities (somehow executing arbitrary code in tauri's webview, for instance).

I remember looking into this and there being another complication.

From what I understand, the deep link plugin would open another instance of the launcher to handle the link, unless you also use the single instance plugin.

Single instance isn't a deal breaker-- I think it's the more intuitive behavior, personally-- but I'm not sure what our use patterns look like for e.g. people running multiple instances of the game at once. Are they already using the "keep launcher open at launch" config option? Or are they gonna be confused when they can't open the launcher multiple times?

Think we gotta discuss which route is best
