Add optional stdio transport to marketing example servers
When launched with --stdio flag, servers use StdioServerTransport instead of starting an HTTP server. This enables direct integration with Claude Desktop and other MCP clients that use stdio transport. Usage: bun examples/budget-allocator-server/server.ts --stdio 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
