dev-up

One-verb local dev-server + worktree QA lifecycle for any checkout (web or Expo), backed by a Cloudflare-Tunnel ngrok replacement that multiplexes many dev servers (via portless) through one wildcard subdomain. Includes `dev-up`/`dev-down`/`dev-status` (env seeding, install, portless naming, public URL), `setup.sh` (one-time machine onboarding), `add-project.sh` (per-project tunnel wiring), `metro-takeover.sh` for switching Expo Metro between git worktrees, `expo-qa.sh` (fingerprint gate that detects when a worktree needs its own dev build or the installed dev client is stale, plus `eas update --branch wt/<branch>` publish for parallel branch QA on any dev client), `worktrees-gc.sh` for pruning landed agent worktrees in any repo, and `doctor.sh` for health-checking the tunnel/portless chain. Formerly named cloudflare-tunnel-portless. Triggers on "dev-up", "spin up the dev server", "start the dev server", "test before shipping", "public URL for this worktree", "set up cloudflare tunnel", "onboard new mac to tunnel", "add project to tunnel", "ngrok replacement", "public URL for localhost", "portless", "cloudflared", "metro-takeover", "switch metro to worktree", "expo-qa", "fingerprint gate", "is the dev client valid for this branch", "publish this branch as an EAS update", "QA this worktree on my phone", "worktrees-gc", "clean up worktrees", "prune old worktrees", "tunnel doctor", or "debug caddy/portless/cloudflared".
