Bump version to 0.1.7 in PKGBUILD, Cargo.toml, and README

- Refactor `render_help` to display tabbed UI for help topics.
- Introduce `help_tab_index` to manage selected tab state.
- Allow navigation between help tabs using Tab, h/l, and number keys (1-5).
- Enhance visual design of help sections using styled tabs and categorized content.
- Update input handling to reset tab state upon exit from help mode.
