# Fresh install CI — validates the released mcpp binary via xlings.
# Simulates a real first-time user on a clean machine (no caches).
#
# For each platform, tests every supported toolchain:
#   1. mcpp new hello → mcpp run (basic project)
#   2. mcpp build (build mcpp itself from source)
#
# This workflow tests released mcpp, not PR code.
# It runs on release publish, manual trigger, and daily schedule.
