Maxim 836e7c786f ci(sdk-python): add an ag-ui-langgraph 0.0.43 regression leg
The matrix covered the declared floor (0.0.42) and the newest release
(0.0.44) but skipped 0.0.43 — the only still-supported version that
reproduces the failure this PR fixes.

0.0.43's `LangGraphAgent.clone()` passes its three behavior flags to
`type(self)(...)` unconditionally, so a subclass with a closed signature
raises TypeError on the default construction path — a 500 on every
request, since the FastAPI endpoint clones per request. 0.0.44's
`clone()` is signature-aware and omits default-valued flags a subclass
cannot accept, which means the clone tests pass on 0.0.44 even with the
`**kwargs` passthrough removed. The `emit_raw_events=False` test still
guards option reachability there, but nothing in the matrix reproduced
the default-construction 500 itself.

Verified locally against 0.0.43: all four clone tests pass with the
passthrough and all four fail without it, so the leg is a real guard.

One representative Python (3.12) via `matrix.include` rather than a
third full column — the flag forwarding it exercises is not
version-specific, so this adds one leg, not five. Installed in the leg
rather than declared, so the runtime floor stays at 0.0.42 and the
effective LangGraph floor stays at >=0.3.25 for consumers.

Also corrects the `test_agui_agent_clone.py` module docstring, which
claimed CI exercised 0.0.42 and 0.0.43 while the workflow installed
0.0.42 and 0.0.44.
