Fix silly double config parsing in pyodide agent

- Remove redundant tempConfig creation
- Parse CLI args once with parseBaseRuntimeArgs
- Extract syncUrl and authToken directly from parsed config
- Pass adapter explicitly to PyodideRuntimeAgent
- Add proper error handling for missing auth token

This eliminates the silly pattern of parsing Deno.args twice.
