No default timeout for requests (unlike TS SDK)

Initial Checks

• I confirm that I'm using the latest version of MCP Python SDK
• I confirm that I searched for my issue in https://github.com/modelcontextprotocol/python-sdk/issues before opening this issue

Description

Spec states: Implementations SHOULD establish timeouts for all sent requests, to prevent hung connections and resource exhaustion.

The TypeScript SDK does have a default timeout of 60 seconds on requests, and the difference between Python & TypeScript is the crux of https://github.com/modelcontextprotocol/typescript-sdk/issues/245 (which also suggests 60 seconds might not be long enough). Also related, TypeScript has a resetTimeoutOnProgress option (defaulting to falst), which would probably be useful if we do introduce a default to the Python SDK.

issue にはファイル名もテストも記載されていないため、まず Python SDK のリクエスト送信と進捗処理のパスを特定します。動作を TypeScript SDK の 60 秒のデフォルト値および resetTimeoutOnProgress に関する議論と比較します。送信されたリクエストに対して、合意されたデフォルトタイムアウトの動作が実装され、検証されれば完了です。
