- Add comprehensive `--description` flags to all fish functions for better `help` and `functions` output. - Introduce and correct `--wraps` flags to ensure proper completions for aliased commands (e.g., `top` wrapping `btop`, `zellij`, `upgrade` wrapping `paru`). - Prepend descriptive comments before function definitions for better source readability. - Add standard copyright and SPDX license identifiers to shell scripts. - Enhance script robustness by ensuring consistent terminal checks (Kitty, WezTerm) and graceful fallbacks in window/tab spawning functions (`spwin`, `tab`). - Implement graceful fallbacks to basic core utilities when preferred modern alternatives are missing (e.g., `top` falling back to system `top` if `btop` is missing, `view` falling back to `less` or `cat` if `nvim` is unavailable). - Improve overall code consistency across the `functions/` directory.
