SwifterPM is now the default for generated projects

tuist install now uses SwifterPM by default to fetch and restore your Swift package dependencies. Resolution stays with the Swift Package Manager, while restoration links checkouts back to a global content-addressable store instead of copying them into every worktree. Warm restores drop to sub-second, and you stop paying for gigabytes of duplicated checkouts across worktrees.

This used to be opt-in through TUIST_USE_SWIFTERPM=1; now it's on by default. If you hit a package graph SwifterPM doesn't handle yet, set TUIST_USE_SWIFTERPM=0 to fall back to SwiftPM, and please open an issue so we can fix it.
