Package backup implements the `dodo backup` command: an online snapshot of the SQLite database, equivalent to `sqlite3 <db> ".backup <dest>"`.

Package selfupdate lets the dodo-cli and dodo-tui binaries upgrade themselves in place from the project's GitHub releases: it compares the installed version against the latest release, and when a newer one exists it downloads the matching archive, verifies its checksum, and atomically replaces the running executable.
