native-tests.yml

# Story 06 Phase A (#387): execute the native runner unit suites.
# Shape copied from codeql.yml: a fast ubuntu `changes` pre-flight, then
# per-platform jobs that either run the tests or post a green skip notice —
# checks ALWAYS post, so the maintainer's "CI green" merge rule stays sound
# without required-status-check config.
