1.16.0

The client side of service 1.16.0.

• options.examples in the stdio bridge and the tool schemas: pass what you asked the code to do (assert f(2) == 4, or doctest lines) and execute_python checks the code against it in the sandbox. Every other check passes on a function that computes the wrong answer; this is the one that does not.
• The registry listing leads with that: "Proves AI-generated Python does what you asked".
• Pre-commit users: rev: v1.16.0.
