A stack entry's storage may be shared by other copies, so mutation is incompatible with value semantics. We've migrated the motivating use case to another approach. Revert commitb3873b8272(cmFindPackageStack: Allow controlled mutation, 2025-07-29, v4.2.0-rc1~438^2) and commitf2bdc2176f(cmStack: New, mutable stack class, 2025-07-29, v4.2.0-rc1~438^2~1). Record their parent as a second parent of this commit so `git blame` can see the original history of the restored content.
