Detailed Description

Sets the calling thread's AllocTag for the lifetime of the scope, restoring the previous one on exit so guards nest.

Innermost wins: a guard inside a frame stage names the finer owner, and the stage keeps everything the finer guards did not claim. Compiles to nothing without DONNER_HEAP_SIZE_HISTOGRAM.
