fix(e2e): seed from installed graphrag-sdk 0.8.2 instead of cloning HEAD

GraphRAG-SDK released v1.0 (April 16) and force-pushed history during
the release, dropping the pre-v1.0 API surface that the e2e tests were
built against. Cloning HEAD now produces a graph without the
merge_with/combine/import_data/add_node/add_edge/ask Function nodes
the tests interact with.

Switch to analyzing the installed graphrag-sdk package (pinned to 0.8.2
via uv.lock — immutable on PyPI). flask clone stays for autocomplete
variety on set/lo/as substrings. ensure_calls_edges keeps acting as a
safety net for the two required CALLS edges.
