fix(deps): force ws>=8 (top-level dep + override) for @zap-proto/web

@zap-proto/web@0.2.0 has peerDependencies ws>=8 and does
require('ws').WebSocketServer, but a stale hoisted node_modules/ws was
7.5.10 (no named WebSocketServer export) → 'WebSocketServer is not a
constructor' at WS-ZAP attach. Pin ws ^8.18.0 as a root dep + override so
the top-level (where @zap-proto/web resolves it) is 8.x.
