Provide self-contained binaries for the wizard

[BYK]

Currently we tell people to use brew or npx to run the wizard. A typical Android dev (and many others) don't have either on their system. We should provide self-contained binaries for ease of use.

Spotlight does this: https://github.com/getsentry/spotlight/releases/tag/%40spotlightjs%2Fspotlight%402.9.0

It shouldn't be too hard to port the logic here and I'm working on making this packaging system a separate tool itself anyway.

Okay, fossilize is ready: getsentry/spotlight#703

Will implement this in this week.
