After COMBO_FPS_MIC fires, ignore FPS and MIC edge handling until both keys are fully released, preventing stray feature-mode or mic-mute short presses on staggered key release.

Short-press FPS and MIC together toggles g_3d_enable (default on), syncs to tile1 via cc_mic_level 0xFB, and calls audio_ex3d_set_onoff on tile1. D8 green LED shows EX3D on; off when disabled.

Remember last active feature on timeout or combo exit. FPS short press from NONE restores that mode; cycling stays on SYSTEM..MIC only so MIC no longer steps through NONE (double-press issue).

Replace factory-reset elapsed-time comparison with 20ms scan-tick counting. The previous code used 32-bit elapsed against 6s/10s/10.6s 64-bit constants, so trigger thresholds were unreachable and countdown got cancelled instead of firing.

Reset feature_timeout_ticks to 0 whenever VOL+ or VOL- causes an effective step in feature mode (short press and repeat), so active adjustments do not timeout and exit feature mode unexpectedly.
