v3.1.1

Fixes

• Modifier+mouse combos now work out of the box — Bindings like KEY_LEFTALT+REL_WHEEL:1 (Alt+scroll), KEY_LEFTCTRL+BTN_LEFT (Ctrl+click) and similar previously delivered only the mouse part because the modifier had no time to latch into the compositor's keystate before the pointer event arrived. TuxBox now automatically inserts a small delay between the modifier and the mouse event for these combos. No configuration required — modifier_delay is still respected for keyboard-only combos in stubborn apps like GIMP, and if you've set it higher than the new auto-floor, your value still wins.
  • Reported in #39 — affects e.g. Alt+Scroll zoom in DaVinci Resolve.

Docs

• Updated CONFIG_GUIDE.md, GUI_USER_GUIDE.md, and default_mappings.conf to document the new auto-delay behavior and clarify that modifier_delay is for keyboard-only combos.
