Optional OpenCMIS TCK Harness

This directory reserves the integration-test boundary for Apache Chemistry OpenCMIS TCK 1.1.0. The harness is intentionally optional because Java/Maven tooling is not part of the default Python test suite.

Planned invocation shape:

mvn -Dcmis.browser.url=http://127.0.0.1:8000/cmis/compat-tck/browser \
  -Dcmis.repository.id=kontextual-compat-tck \
  test

The first target is a selected Browser Binding subset:

repository information,
type definitions,
navigation,
object reads,
content stream reads,
query subset,
relationships,
change log where supported.

Mutation groups should only be enabled for governed-authoring or compat-tck profiles after the policy and audit gates are implemented.
