Adds 'pulse', which captures the IR eye cameras through SteamVR's own eyetracking --calib mode, reduces each image to patch averages and deletes it immediately, then estimates pulse from skin brightness. Adds heart-check.py to show OSC readings live and compare recordings with an Apple Health export or CSV, and a synthetic Mac BLE strap for relay tests.
