Reverts 259 files that carried unrelated upstream changes through the phase-6 merge: enum class removals (cppcoreguidelines-use-enum-class), scoped_lock→lock_guard conversions (modernize-use-scoped-lock), nodestore Backend API changes (void const* key), .clang-tidy config, test infrastructure deletions, and miscellaneous develop changes. These changes belong on develop, not in the telemetry PR chain. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
