Silta 0.912

Changed: ending_maps default → infra_c11_ending_1/_2/_3
Fixed: debug_trigger key now fires the report instantly (was only acting on map load)
Fixed: tweaks keydown log spam — only logs when [tweaks] is enabled now
Added: verbose hotkey diagnostics — logs every keydown with VK + scancode + extended flag (identifies the exact physical key, e.g. real Insert vs numpad-0)
Added: force backbuffer render [EXPERIMENTAL] — attempt to fix gui disappearing after mat_postprocess_enable is set to 0
