name: Distribute on release

# Fans a published GitHub Release out to the channels that need a nudge.
# PyPI is handled by publish.yml; conda-forge is handled by its autotick bot.
# This workflow event-drives the two channels that would otherwise be manual:
#   - Homebrew tap: rewrite the formula's url + sha256 to the new sdist.
#   - HF Space: factory-rebuild so it reinstalls the latest sdist from PyPI.
# Both wait for the freshly published sdist to appear on PyPI first, since the
# Release event fires in parallel with publish.yml's upload.
