Add deploy/ with nginx config and web deploy script

nginx-waste.conf: serve web/dist/ at root, proxy /ws to anchor (port
8080), SPA fallback for clean invite URLs, immutable cache for assets.

deploy-web.sh: build + rsync to anchor host, skip config.js so the
host's runtime config is not clobbered.
