A Python block sent to a REPL gets the second Enter that ends it

A dogfood agent's `def` sent to python3 sat open at the continuation prompt:
a block whose last line is indented is not over at one Enter, pasted into
3.13's REPL or typed into the old one (checked against python 3.14 in a real
pty, both ways). A send to a Python REPL now adds that second Enter, and the
pty/data recipe in the docs and the 9P skill says to.
