Framework search path response files now survive Derived/ regeneration

Tuist now writes the framework search path response files as part of the graph mapper side effects, after the Derived/ directory cleanup. This fixes the recurring “no such file or directory: ‘@…/Derived/FrameworkSearchPaths/.resp’” build failures when regenerating a project over an existing Derived/ folder, which is common on CI. The fix restores reliable builds for projects with many binary-cached or precompiled dependencies that cross the framework search path consolidation threshold.
