Use visual line counting (accounting for line wrapping) instead of logical line counting for bash tool output in collapsed mode. Now consistent with bash-execution.ts behavior. - Add shared truncateToVisualLines utility - Update tool-execution.ts to use Box for bash with visual truncation - Update bash-execution.ts to use shared utility - Pass TUI to ToolExecutionComponent for terminal width access Fixes #275
