Toolchain Installers

Unlike a monolithic setup script, each install is its own task — meriadoc task install-rust when you just need Rust, without pulling in Python and Docker along the way. Each one is self-contained and idempotent-ish (command -v guards, version pins via env vars), so re-running one to pick up a version bump is safe.

version: v1
