The clap --version flag now shows the git hash alongside the semver
version (e.g. "lore 0.1.0 (a573d69)") instead of bare "lore 0.1.0".
LORE_VERSION is constructed at compile time in build.rs from
CARGO_PKG_VERSION + the short git hash, and consumed via
env!("LORE_VERSION") in the Cli struct's #[command(version)] attribute.
