m1ngsama 298995aa53 Fix critical memory and concurrency bugs ... Fixes three critical bugs that caused crashes after long-running: 1. Use-after-free race condition in room_broadcast() - Added reference counting to client_t structure - Increment ref_count before using client outside lock - Decrement and free only when ref_count reaches 0 - Prevents accessing freed client memory during broadcast 2. strtok() data corruption in tui_render_command_output() - strtok() modifies original string by replacing delimiters - Now use a local copy before calling strtok() - Prevents corruption of client->command_output 3. Improved handle_key() consistency - Return bool to indicate if key was consumed - Fixes issue where mode-switch keys were processed twice Thread safety changes: - Added client->ref_count and client->ref_lock - Added client_release() for safe cleanup - room_broadcast() now properly increments/decrements refs This fixes the primary cause of crashes during extended operation.		2025-11-30 09:00:00 +08:00
