Allow the MCP server to be run by `uvx` remotely (#336)

* feat: add entry point script and additional Python modules to server package

Now we can run this server with `uvx`

* refactor: improve package version detection to support both installed and development environments

* refactor: simplify release workflow by removing server packaging step
