migrate server to Streamable HTTP transport

[0hmX]

/claim #2

This commit migrates the MCP server from the deprecated STDIO transport to the new Streamable HTTP transport, as required by the Smithery platform.

The main changes include:

• Updating smithery.yaml to use the typescript runtime.
• Refactoring src/index.ts to export a createServer function for the Smithery CLI, while maintaining backward compatibility with STDIO for local development.
• Updating package.json with the new dependencies and scripts for building and running the server in both HTTP and STDIO modes.

We now have the following commands

to start in legacy

npm run start:studio

and for the new HTTP transport layer

npm run start:http
