refactor(install): move program files to ~/.local/share/floppy-utils

Installs the core script + lib/ under XDG_DATA_HOME/floppy-utils and generates thin wrappers in ~/.local/bin. Updates floppy resolver, install.sh, README, and adds early returns in check-deps logging helpers.

 There is no daemon. Scripts use `sudo` when not root for `dd`, `blockdev`, `losetup`, and mount operations.
 
+After `install.sh`, the main script lives at `~/.local/share/floppy-utils/floppy`; `~/.local/bin/floppy` is a wrapper that finds it.

+This installs the library to `~/.local/share/floppy-utils/` (including `lib/common.sh`) and places small wrapper scripts in `~/.local/bin/`. You can still run `./src/floppy` directly from a git checkout.
