Subject: [PATCH] feat(ci): Add clang-tidy static analysis to CI pipeline
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add .clang-tidy configuration with focused checks for critical issues
- Add Makefile with parallel clang-tidy execution target
- Fix performance issue: remove unnecessary std::move on trivially-copyable type
- Fix bug: remove self-assignment in metadata_server initialization
- Fix unused value warning in transfer_metadata_test.cpp
- Add [[maybe_unused]] attribute to intentional padding fields
- Integrate clang-tidy check into GitHub Actions CI workflow
