Ludovic's decision (2026-10-27). `nightly.py prune-builds` runs in the
scheduled `pick` only, with main's code, and lists each deletion in the run
summary. It deletes only branches named nightly/build-<date>-<n> older than
7 days, never the newest build, and never one a published `nightly` or
nightly-<date> release points to. nightly-state and every other branch are
left alone. tests/test_nightly.py pins it.
