Summary

This pull request introduces a new configuration option that allows users to enable or disable bold font styling in tmux-power segments.

Changes

• Added a new user option: @tmux_power_use_bold (default: false)
• Updated segment rendering logic to conditionally apply bold formatting based on this setting
• Ensured backward compatibility — existing themes and configurations remain unaffected when the option is not set
• Updated README to document the new option and provide usage examples

Example Usage
