#1347 passed the supported Python range to the remote install.sh as
INFINITO_PYTHON_REQUIRES. Every INFINITO_* name is a key of the generated
.env, so test_every_referenced_infinito_key_is_registered fails on main
for this one, which no registry entry can carry: its value is derived
from pyproject.toml's requires-python, the single source, and a default
in default.env would be a second copy of the range. The task environment
and the script now call it DEV_PYTHON_REQUIRES; behaviour is unchanged.
