🐛 Restore CONTRIBUTING.md from pre-corruption state

Reverted to b2b85fc (first kettle-jem v1.0.0 template run) which was
the last clean version. Subsequent runs duplicated the tool list,
coverage ENV vars, spec organization rules, rubocop gradual section,
and release steps — each block copied once per template run.

 For a quick starting point, this repository’s `mise.toml` defines the shared defaults, and `.env.local` can override them locally. Copy `.env.local.example` to `.env.local`, use `KEY=value` lines, and either activate `mise` in your shell or run commands through `mise exec -C /path/to/project -- ...`.
