Estimated code review effort

🎯 2 (Simple) | ⏱️ ~8 minutes

• Verify that removal of log_state_rocksdb_cloud_impl.cpp does not break any dependencies or link targets
• Confirm that adding log_utils.h include is necessary and resolves any undefined symbols
• Check that documentation and CMake changes are aligned in intent

Poem

🐰 A log state removed with care,
The cloud's S3 no longer there,
Build scripts lean, and sources clean,
Utils now where once obscene—
One include added, paths refined! 📚✨

Docstring Coverage	⚠️ Warning	Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%.	You can run @coderabbitai generate docstrings to improve docstring coverage.
Title Check	❓ Inconclusive	The title "fix compile doc" is too vague and generic to clearly convey the actual changes in the pull request. While the changeset does include modifications to the documentation file (docs/how-to-compile.md), the PR also involves source code and CMake configuration changes (removing a source file from the build and adding an include). The terms "fix" and "doc" are non-descriptive and don't communicate what specifically is being fixed or what the primary change entails. Additionally, the PR description is marked as "wip" (work in progress), suggesting the PR may be incomplete, which compounds the ambiguity of the title.	Consider revising the title to be more specific and descriptive. Instead of "fix compile doc," consider a title that captures the actual intent of the changes, such as "Remove log state variable from compile documentation and build config" or similar language that more precisely describes what is being removed and why. Additionally, complete the PR description beyond "wip" to provide context about what issue or objective this PR addresses.
