feat(cli): include command name in error messages and crash reports

Implement TODO in handleCommandError:
- Log command name with error for crash report context
- Display 'Error in \'{s}': {s}' instead of generic 'Error: {s}'
- Helps users identify which command failed

Build verified: zig build --release=fast
