v0.1.3

feat(detection): real-hardware tap detection with typing suppression

Replace the simulated accelerometer pipeline with working IOKit-based access
to AppleSPUHIDDevice, so physical palm-rest taps on Apple Silicon MacBooks
actually fire events. The essential fix: wake-up properties must be written
to AppleSPUHIDDriver nodes (not the device), or the sensor stays dormant.

Detector rewritten as a refractory-and-release state machine so a single
physical tap (with its damped oscillation) counts as exactly one tap.
Thresholds re-tuned empirically for palm-rest signal levels (~0.02g peaks).

Global CGEventTap suppresses typing-induced vibrations: samples within 200ms
of a keystroke are dropped, and tap emission is deferred 500ms so any key
event during that window cancels the tap.

App side: Simulate and Mode settings removed from the menu (Simulate was a
dev crutch, Desk mode was never calibrated). Test Mode + auto-start are the
defaults. Sidecar runs under setuid-root via a one-time admin prompt, and
notifications now go through osascript (reliable without signed entitlements).
