Fixes thread accumulation and blocking issues: 1. SSH read timeouts - Use ssh_channel_read_timeout() with 30s timeout - Handle SSH_AGAIN, SSH_ERROR return codes properly - 60s timeout for username input - Prevents threads blocking forever on dead connections 2. Improved PTY request handling - Exit loop after PTY + SHELL received - Don't loop on WINDOW_CHANGE during init - Clear termination conditions 3. Better UTF-8 validation - Check multi-byte read completeness - Skip incomplete sequences gracefully Prevents "zombie threads" and eliminates need to restart after extended operation.
