Engine-agnostic memory plan for a single profiling run.

Produced by the ``plan_memory`` stage by combining engine-specific
knowledge (AOT arena regions, TFLM single-arena size, weight placement)
with the SoC's physical memory layout.  Consumed by the report and by
the firmware template generator for placement macros / linker hints.
