Remove HTTP server mode, keep MCP + CLI only

Drop express dependency and HTTP server in favor of MCP-only architecture.
CLI still works for quick screenshots and queries.

- Delete src/server.ts and src/server.test.ts
- Remove express, @types/express, supertest from dependencies
- Update CLI to show help when no URL provided
- Remove server exports from index.ts

-33 packages removed, 757 lines deleted.
