The satisfy refactor tool stops crashing on type errors while the compiler team reorganizes global config across the SSA pipeline.

Peter Weinberger landed a critical fix to golang/tools that prevents nil dereference crashes in the refactor/satisfy tool when processing code with type errors [1]. The fix addresses issue golang/go#73109 and closes a gap where multiple cases of malformed input could tank the refactor workflow. Meanwhile, Michael Matloob pushed two related changes to golang/go reshaping how the compiler's SSA backend handles global configuration [2][3]. The work moves config state from scattered globals into a dedicated ssaconfig package, preparing for a larger refactoring of compiler passes slated for #80409. Both changes reflect ongoing structural cleanup inside the compiler toolchain with minimal user-facing impact today.
