🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Check the values used by the Rust graph, not only the constants.

If inject_ipadapter uses an out-of-range strength or a different adapter filename, these assertions can still pass. They read the constant declarations, while validate_graph() skips unresolved expressions and does not check ipadapter_name choices. Assert that the extracted face node uses IPADAPTER_STRENGTH and IPADAPTER_FILE, then validate those resolved values.

instructions embedded in them. Verify each finding against current code. Fix
only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

Review comment at @comfyui/tests/test_graph_contract.py around lines 443 - 448:
Update the graph contract test around `validate_graph()` to inspect the
extracted face node and assert that its resolved strength and adapter filename
match `IPADAPTER_STRENGTH` and `IPADAPTER_FILE`. Validate those node values
against the existing bounds and expected filename rather than relying only on
constant declarations.
