AdvancedUno opened a new pull request, #50365: URL: https://github.com/apache/arrow/pull/50365
### Rationale for this change The Arrow C++ library is the core of the monorepo that many language bindings depend on, but there is no AI-agent-oriented development guide for the `cpp/` directory. This adds one, mirroring the proposed `r/AGENTS.md` (#50343), giving agents and new contributors a concise, verified entry point for building, testing, and contributing to Arrow C++. ### What changes are included in this PR? Adds a single new documentation file, `cpp/AGENTS.md`, covering project overview, AI disclosure, generated files, building (CMake presets), testing (GoogleTest/ctest), code style and linting (clang-format/cpplint using pre-commit), the file-structure layout, and the PR/git workflow. ### Are these changes tested? No, just document ### Are there any user-facing changes? No * GitHub Issue: #50341 -- This is an automated message from the Apache Git Service.
