Dylan DeverillandClaude Fable 5 b80c7b830e Overhaul trackpad haptics: fix firmware lizard revert, click latch, tick gating
The core fix: the SC2026 firmware silently reverts to lizard mode (including
its autonomous click haptics) after a period without host feature reports,
which doubled up with software haptics as a crunchy burst. A keepalive now
re-asserts the lizard-off state every 2 seconds while game mode is active.

Haptics reliability and feel:
- Switch trackpad haptics from OUT_HAPTIC_PULSE (grip LRAs) to
  OUT_HAPTIC_COMMAND (trackpad LRAs) for localized feel
- Click haptic latch: press fires off the debounced firmware click bit,
  release only fires once contact area returns to idle, so force chatter
  and mid-hold easing cannot re-fire
- Movement ticks: distance-based with motion deadzone, post-release and
  first-touch grace windows, pressing/teleport gates (pause, not reset),
  idle decay, and a 50ms send rate limit so firmware waveforms never queue
  into a backlog

Handoff and mouse:
- EnableLizardMode now also sends LOAD_DEFAULT_SETTINGS so firmware mouse
  emulation resumes immediately on disable instead of waiting for the
  firmware revert timeout
- Trackpad mouse: carry sub-pixel movement remainders between frames and
  retune sensitivity (0.015 -> 0.01125)

Also: shared/exclusive HID reopen support, local-only HapticTester tool
(gitignored, conditional CMake target), installer version bump to 1.7.
