Run Cherries Experiments

Use this skill for Cherries experiments and saved records. Read the Cherries checkout's docs/README.md before relying on a command; installed versions may not yet include every documented capability.

Repository boundary

Work in the separate experiment superproject, for example:

phace-exp/
  cherries.toml  pyproject.toml  uv.lock
  libs/apple/  libs/melon/       # Git submodules
  exp/YYYY/mm/dd/study/
    src/  configs/  fixtures/  docs/  analysis/
