Review fixes for the pack's offline checks.
- The startup version reader and the checks read pyproject.toml as TOML
instead of a regex.
- validate_nodes and registry_contract catch more ways a node mapping
or the module list could be hidden from registry scanners.
- release_preflight flags network-client imports and spaced or
qualified fetch calls in shipped code.
- workflow_contract verifies saved widget values against the real
widget order, covers subgraphs and validates model download info.
- Krea 2 Inpaint Masked example: two Note nodes' named widget values
now match their positional values, which the new check requires, and
the file ends with a newline. The graph itself is unchanged.
Tests: tests/test_check_regressions.py, with one adjusted case in
tests/test_workflow_contract.py.
No inputs, outputs or mapping keys change. No version change.
