"""Regenerate CMakePresets.json — one uniform pipeline per chip.

Every chip gets generated-mode configure/build/test presets and a workflow
running all three. Reflect-mode presets (configure + build, no tests — the
port's TUs compile identically; the sims prove nothing new there) exist for
libavr's reflect spot set only, mirroring its rule: the full reflect matrix
is never built, one chip per hardware class and pack vintage is.

Run from the repo root: tools/make_presets.py
