build(deps): require anthropic>=1,<2

This PR makes the messages API work with the 1.x anthropic client
(routes `temperature` through `extra_body` instead of the typed kwarg
that 1.x removed), and the lock already resolves 1.2.0. Bump the
dependency floor to `>=1` so the declared constraint matches what the
code targets, and cap at `<2` so the next major can't silently break us
the way 1.x did.
