feat: add build script for version info and shell completions

Introduce a build.rs that generates a version.txt file with the
package version, git commit hash, and date. Also generate shell
completion scripts using mingling's build utilities.

Migrate the `-v/--version` flag to read from the generated
version.txt and replace BasicProgramSetup with HelpFlagSetup.
