Restore left-edge tap navigation in display rotator

[Codex]

Restores left-side tap handling by calibrating touch width from live input data so taps on both edges are correctly classified.

Changes

• Track observed X min/max positions in display_rotator.py to derive an accurate touch width even when sysfs absinfo is missing.
• Use the calibrated bounds to map taps to PREV/NEXT while keeping double-tap screen toggle behavior intact.

Testing

• python3 -m compileall display_rotator.py

Addressed by calibrating touch width from observed events so left taps map to PREV; see commit 912baff.

Saw the linked commit comment—current change in 912baff adds dynamic touch width tracking so left taps emit PREV; let me know what specific behavior is still off and I’ll adjust.

Summary

• Fixed tap-direction classification to use the observed touch range midpoint (min_seen..max_seen) instead of the device-reported absolute width, which prevents left taps from being misclassified on controllers that report a compressed sub-range. display_rotator.pyL381-L386
• Added inline comments documenting why observed-range midpoint is the correct split for PREV/NEXT behavior. display_rotator.pyL382-L385
• Committed the change on the current branch (105c01c) and created a follow-up PR titled “Follow-up: fix left/right tap split using observed touch range”.

• ✅ python -m py_compile display_rotator.py
