Build insights find DerivedData for projects with spaces in the name

Build insights collection now locates Xcode activity logs for projects whose filename contains a space. DerivedDataLocator mirrors Xcode’s behavior by replacing spaces in the project / workspace name with underscores before appending the path-based MD5 hash, so tuist inspect build (and Xcode scheme post-actions that use it) finds the generated .xcactivitylog instead of searching a non-existent directory.
