Add Vercel

This skill gives NanoClaw agents the ability to deploy web applications to Vercel. It installs the Vercel CLI in agent containers and configures OneCLI to inject Vercel credentials automatically.

Principle: Do the work — don't tell the user to do it. Only ask for their input when it genuinely requires manual action (pasting a token).

Phase 1: Pre-flight

Check if already applied

Check if the container skill exists:

test -d container/skills/vercel-cli && echo "INSTALLED" || echo "NOT_INSTALLED"

If INSTALLED, skip to Phase 3 (Configure Credentials).
