/// For *all* builds, the CLI spins up a dedicated webserver, file watcher, and build infrastructure to serve the project.
///
/// This includes web, desktop, mobile, fullstack, etc.
///
/// Platform specifics:
/// -------------------
/// - Web:         We need to attach a filesystem server to our devtools webserver to serve the project. We
///                want to emulate GithubPages here since most folks are deploying there and expect things like
///                basepath to match.
/// - Desktop:     We spin up the dev server but without a filesystem server.
/// - Mobile:      Basically the same as desktop.
///
/// When fullstack is enabled, we'll also build for the `server` target and then hotreload the server.
/// The "server" is special here since "fullstack" is functionally just an addition to the regular client
/// setup.
///
/// Todos(Jon):
/// - I'd love to be able to configure the CLI while it's running so we can change settings on the fly.
/// - I want us to be able to detect a `server_fn` in the project and then upgrade from a static server
///   to a dynamic one on the fly.
