test(canonical): align live harness docs and result stub

[Q00]

Summary\n\n- Refreshes canonical fixture docs now that the live opt-in path exists.\n- Replaces the local Result-shaped _Ok stub with Result.ok so the harness test uses the real Result contract.\n\n## Changes\n\n- Updates tests/canonical/conftest.py docstring.\n- Updates tests/canonical/test_canonical.py to use Result.ok and property-based Result access.\n\n## Notes\n\nFollow-up for #1214 stale docs and the coordination note raised from #1218.

What Improved

• Canonical live-run test now uses the real Result property API (is_ok, is_err, error) instead of the old callable/fake shape.
• Canonical fixture docs now describe the existing OUROBOROS_RUN_CANONICAL=1 opt-in path accurately.

Test Coverage Notes

• Reviewed tests/canonical/test_canonical.py, tests/canonical/conftest.py, tests/canonical/test_conftest.py, src/ouroboros/core/types.py, and src/ouroboros/mcp/tools/auto_handler.py.
• Verified syntax for changed canonical files with python3 -m py_compile tests/canonical/test_canonical.py tests/canonical/conftest.py tests/canonical/test_conftest.py.
• Could not run pytest: uv is not installed, pytest is not installed for system Python, and the snapshot declares Python 3.14 while the container only has Python 3.11.2.

Design Notes

The change is scoped to test harness correctness. It aligns the canonical live-run test with the project-wide Result contract without altering runtime code.

Design / Roadmap Gate

Affected boundary is the canonical acceptance harness calling AutoHandler.handle. Current HEAD evidence shows AutoHandler.handle returns Result[MCPToolResult, MCPServerError], and Result exposes is_ok, is_err, and error as properties. The PR removes the previous local fake that masked this contract and makes the hermetic opt-in test exercise the same shape as the live path.

Directional Notes

Maintainer memory emphasized docs/runtime honesty, so I checked that the updated fixture documentation matches the implemented opt-in live-run path and the real AutoHandler.handle return type.

Test Coverage

• Reviewed tests/canonical/test_canonical.py, tests/canonical/conftest.py, tests/canonical/test_conftest.py, src/ouroboros/core/types.py, and src/ouroboros/mcp/tools/auto_handler.py.
• Verified syntax for changed canonical files with python3 -m py_compile tests/canonical/test_canonical.py tests/canonical/conftest.py tests/canonical/test_conftest.py.
• Could not run pytest: uv is not installed, pytest is not installed for system Python, and the snapshot declares Python 3.14 while the container only has Python 3.11.2.

Merge Recommendation

Approve. I found no blocking runtime, contract, persistence, or test-harness regressions in the changed boundary. Test execution is limited by the local environment, but direct source inspection and syntax checks support the change.
