Use Case

As a... Node.js Driver Developer
I want... to replace all usages of the global process.arch property with the method os.arch().
So that... I can standardize on the os module for system information, reducing reliance on the process global which is often missing or shimmed incorrectly in non-Node environments.

User Experience

• None; This is an internal refactor. The functionality (detecting system architecture for handshake/metadata) remains identical.

Dependencies

• None

Risks/Unknowns

• os.arch() is a standard Node.js API that returns the same string values (e.g., 'x64', 'arm64') as process.arch

Acceptance Criteria

• Replace any usages of process.arch with os.arch()
