feat(shell): add poke function and update fish-deps for ov and yay

- Add poke: touch with automatic parent directory creation; prints
  colored notice when new dirs are created; handles multiple file args
- Refactor config.fish CachyOS override block: consolidate copy into
  the erase+source loop alongside ls/lt/cleanup
- fish-deps: replace most with ov (cargo crate + AUR pkg); add yay as
  rec dep with yay-build special (paru -S yay or AUR makepkg); add
  update handling for yay-build in _fish_deps_update
- README: document poke in Directory & File Listing table
