Removed outdated `syu` symlink which just hooks into topgrade.
Replaced it with simple function that tries for topgrade, paru, yay,
pacman, in that order. Can still be invoked with simple `syu` command,
but *only* through interactive terminal use.
Switched git pre-commit hook to default to paru instead of yay when
compiling installed package lists for dotfile commits.
Fixed paths to images for new repository dotfile delineation. Added
quick readme blurb explaining differece of normal and dotfile
directories.
Readme still explained old bare-repository directory structure. Rewrote
sentences to conform to new structure.
Removed underscore from bootstrap directory, since the repository does
not organize itself through underscore prefixes anymore.
Fixed package gathering git-hook to respect new bootstrap directory.
When moving to commit, this hook will automatically fire and check the
current system's installed packages against those explicitly committed
to the repository. If they mismatch it will inform the user.
It will not prevent the commit, but simply add a comment at the top of
the commit messages to remind the user that something is unbalanced
between both. It would be recommended to either check the additional
package into source control, remove it from the current system, or
explicitly add it to ignored packages.
