v0.3.1 — Documentation cleanup (remove internal-only IDs)

v0.3.1 — Documentation-only cleanup. No code, requirement, design, or test artifact changed.

What changed

The v0.3.0 distribution shipped with internal project IDs (BUG-007 / BUG-008 / BUG-009, FR08-* / NF08 / NF09, V03-*) embedded in README.md, docs/SETUP.md, docs/GETTING_STARTED.md, docs/HARNESS_GUIDE.md, and harness/skills/cognee-queue-flush/SKILL.md. These IDs are only meaningful inside the development project and provide no value to recipients of the distribution.

v0.3.1 removes them all (27 occurrences across the English and Japanese distributions, fixed one by one in individual commits) and rewrites the surrounding sentences in concrete user-facing terms (e.g. "the Ladybug DB lock contention error 'Could not set lock on file'" instead of "BUG-008"). One reference into the development project (Architecture rationale: BUG-008 fix_plan in the project documentation) was redirected to the v0.3.0 entry of CHANGELOG.md.

Use this release if you are reading the bundled docs cold and do not have access to the development project. Otherwise v0.3.0 and v0.3.1 are functionally identical.

See claude-code-tools/claude-code-cognee-graph-memory/CHANGELOG.md for the full v0.3.1 entry.
