Add bare-minimum extension-reaper-macos REAPER extension skeleton

C/C++ extension built directly against the vendored Cockos reaper-sdk headers (no Rust/reaper-rs wrapper layer). Loads, registers a test action, and confirms via REAPER's console — confirmed working in REAPER 2026-07-15. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
