The agent's global Node CLIs (claude-code, agent-browser, vercel) were each
a hardcoded ARG + RUN layer in the Dockerfile, so adding or bumping one meant
editing the Dockerfile — a code reach-in every tool-installing skill had to make.
Move the tool list into container/cli-tools.json. A skill now adds a CLI by
appending a {name, version} entry (a json-merge) — the safest change shape:
deterministic, idempotent, removable. install-cli-tools.sh parses the manifest
with node (no new jq dep), writes the per-tool only-built-dependencies opt-ins,
and runs one pinned `pnpm install -g`, so the pnpm supply-chain path is unchanged.
Behavior is byte-for-byte: same opt-ins, same pinned installs. agent-browser is
now pinned (0.27.1, what `latest` last resolved to) instead of floating.
container/cli-tools.test.ts guards the seam: red if a baseline tool is dropped,
a version unpins, or the Dockerfile wiring / pnpm path is removed.
