Port probe to zero-dep plain ESM (setup/probe.mjs) so /new-setup can
inject dynamic context on a fresh machine where pnpm/node_modules
don't yet exist. Skill falls back to a STATUS: unavailable block if
Node itself isn't on PATH, and the flow treats that as "run every
step from 1" (each step is idempotent).

Shortest path from zero to a working two-way agent chat via the CLI
channel. Renders `!`pnpm exec tsx setup/index.ts --step probe`` at the
top for dynamic context injection — Claude sees current system state
before generating its first response and routes each subsequent step
(skip/ask/run) off the probe snapshot. Pre-approves the Bash patterns
it needs via `allowed-tools` so setup runs without per-step prompts.
Lives alongside /setup for now; will replace it once proven.
