v0.11.1

Fixed

• ADR-002 restored. attune-author is no longer a required dependency
  of attune-help — moved back to the [authoring] optional extra. The
  0.11.0 release note that declared attune-author>=0.7.0 as a new
  required dep was a regression against ADR-002 ("zero required deps
  beyond python-frontmatter"); this release reverses it. Users who
  consume the deprecated attune_help.manifest / staleness /
  freshness shims now get a clear ImportError pointing them at
  pip install attune-help[authoring] instead of a transitive install.

Added

• 44 new tests across 5 new files (309 passing total): zero-dep
  install smoke test (real venv, @pytest.mark.slow), reusable
  StorageProtocolTester mixin, direct _find_template_file /
  _parse_template_file / cache tests (incl. CWE-22 path-traversal
  guard), AttuneHelpAdapter protocol-conformance tests, and direct
  unit tests for _require_str + the MCP engine/server factories.
• Branch-coverage gate at 81% (currently 82.31%), enforced via
  pyproject.toml's [tool.coverage.*] + a coverage cell on the
  ubuntu-latest × py3.11 matrix entry in CI. Coverage report
  uploaded as an artifact.
• New test-no-authoring-extra CI job that verifies the
  pytest.importorskip("attune_author") skip path actually works
  when the optional extra isn't installed.
• live pytest marker registered (deselected by default via
  addopts = "-ra -m 'not live'"). attune-help makes no LLM calls
  today; the marker is reserved so future tests have a consistent home.
• CI guard against ANTHROPIC_API_KEY in the default test env —
  fails fast as a regression alarm in both the matrix job and the
  test-no-authoring-extra job.

Changed

• tests/README.md replaces its inline LLM-mocking section with a
  pointer to the workspace-level testing-conventions.md (umbrella
  spec). Single source of truth across the attune-* family.

Dependencies

• Correction: the 0.11.0 entry incorrectly declared
  attune-author>=0.7.0 as a new required dependency. It was always
  intended to be the [authoring] extra; 0.11.0 shipped with it
  required by mistake, and 0.11.1 restores the intended shape. No
  action needed for users who installed attune-help[authoring];
  users who installed bare attune-help and hit shim ImportErrors
  should add the [authoring] extra explicitly.
