fix: default desktop mode opens the browser.

- Cross compilation becomes A LOT more complicated
  once CGO is in the mix. Requires the time and energy
  to get build scripts to work across all platforms, and
  update the automated Github Actions to build on
  multiple machines (MacOS requires MacOS runner,
  Windows / Linux require Linux runner)
- This commit adds a build flag "webview" to enable
  webview desktop support but the default without
  the build flag is to open the browser on start.
