name: Membrowse Zephyr Report

# Triggered after the heavy Zephyr 4.x test workflow completes. Pulls the
# pre-built zephyr.elf, zephyr.map and linker.cmd artifacts staged by
# zephyr-test.sh and feeds them to the Membrowse memory-tracking service.
# This avoids duplicating the (slow) Zephyr build inside the Membrowse
# matrix.
