Addresses review feedback on #5152:
- Revert the mem0/__init__.py module docstring (was a misguided
workaround to fire ci.yml; reviewer correctly flagged as unrelated)
- Bump cli-python and cli-node to 0.2.6 so the claim-flow tip wording
fix ships to users in the next release
- Add CLI v0.2.6 changelog entry under docs/changelog/sdk.mdx
The build_mem0/build_embedchain required-check stalemate on docs-only
PRs needs a proper ci.yml fix in a separate PR (passthrough job for
the path-filter-skipped case). Admin override needed for this PR.
