fix(tsconnect): skipLibCheck to avoid monorepo @types conflicts

When tsconnect is built inside a JS monorepo, TypeScript walks up the
directory tree and auto-discovers @types/eslint-scope and @types/ws
from the root node_modules, causing spurious type errors unrelated to
tsconnect itself. skipLibCheck suppresses these.
