bakery.toml: bread-theme + awww/pywal, not bread

The setter shells out to awww, wal, and bread-theme reload. It never
talks to breadd. bakery.toml listed bread as a dep and treated awww as
optional.

Add a short README: this is a setter, not a library or slideshow
daemon. Wallpaper library UI lives in bos-settings.

+# breadpaper
+
+Wallpaper setter for the bread desktop. One command sets the wallpaper
+via [awww](https://github.com/heywoodlh/awww), generates a palette with
+[pywal](https://github.com/dylanaraps/pywal) (`wal`), and runs
+`bread-theme reload`.
+
+It is not a wallpaper library, a slideshow daemon, or a GUI. Browsing
+`~/Pictures/Backgrounds` and picking an image lives in
+[bos-settings](https://git.breadway.dev/Breadway/bos-settings).
+
+## Dependencies
+
+Must be on `$PATH` for `set`:
+
+- `awww` — Wayland wallpaper (`awww img`)
+- `wal` — palette generation (`python-pywal`)
+- `bread-theme` — theme reload (bakery package, not `breadd`)
+
+`get` only reads the path pywal stored at `~/.cache/wal/wal`.
+
+## Install
+
+```
+bakery install breadpaper
+```
+
+From source:
+
+```
+cargo build --release
+install -Dm755 target/release/breadpaper ~/.local/bin/breadpaper
+```
+
+## Usage
+
+```
+breadpaper <path>          # shorthand for `set`
+breadpaper set <path>      # awww + wal + bread-theme reload
+breadpaper get             # print the current wallpaper path
+```
+
+Supported formats: `png`, `jpg`, `jpeg`, `webp`, `gif`, `bmp`.
