fix: improve CachyOS kernel hook robustness and branding consistency

- Implement robust fallback loop for CachyOS kernel package suffixes (-3, -2, -1) with curl verification.
- Standardize branding tagline to "Switch to simple" across Plymouth and MOTD.
- Rename "Keyboard Shortcuts" to "KibaOS Shortcuts" in kiba-welcome script.
- Fix trailing whitespace in kiba.yml workflow.
