Fix duplicate @types/node in TS manifest and address Python test lint/type issues

[GsCommand]

Motivation

• Ensure the repository can pass Phase 2 gates by removing manifest drift in the TypeScript package metadata and clearing Python lint/type failures that block ruff/mypy/pytest validation.
• Make the minimal, surgical edits required to restore internal coherence around v1.1.0 without changing public API or upgrading unrelated dependencies.

Description

• Removed the duplicate/conflicting @types/node entry from typescript-sdk/package.json and normalized the devDependency to a single entry (@types/node: ^22.7.5).
• Synchronized the root devDependencies entry in typescript-sdk/package-lock.json to match the manifest.
• Fixed Python test lint and typing issues by reformatting a long import line, wrapping a long assertion, and casting json.loads(...) results to dict[str, Any] in python-sdk/tests/parity_report.py, python-sdk/tests/test_public_api.py, and python-sdk/tests/test_verification.py to satisfy ruff and mypy without altering behavior.
• Files changed: typescript-sdk/package.json, typescript-sdk/package-lock.json, python-sdk/tests/parity_report.py, python-sdk/tests/test_public_api.py, python-sdk/tests/test_verification.py.

Testing

• cd python-sdk && ruff check . — PASS.
• cd python-sdk && mypy . — PASS.
• cd python-sdk && pytest — PASS (23 tests, 1 warning).
• cd typescript-sdk && npm ci — FAIL due to environment package acquisition (devDependencies could not be installed in this environment), blocking further TS install-dependent gates.
• cd typescript-sdk && npm run typecheck — FAIL because @types/node and other devDependencies were not installed from npm ci.
• cd typescript-sdk && npm test — FAIL because tsup (devDependency) is not installed when npm ci cannot complete.
• cd typescript-sdk && npm pack --dry-run — FAIL because the prepack build step cannot run without installed devDependencies.
• cd python-sdk && python -m build — FAIL because build tooling was not available in the environment and pip install was not possible here.
• cd python-sdk && twine check dist/* — FAIL because twine was not available in the environment.

Note: All source fixes described above were applied and validated locally where possible; remaining failing gates are due to missing external tooling or blocked package acquisition in the execution environment and not due to source defects introduced by these edits.
