Fix bash tool visual line truncation

Browse source 
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
