candle-graph 0.10.0

//! Single shared Clap definition for `candle-graph` and `cargo candle-graph`.
//!
//! Both binaries parse the same [`Cli`]; the cargo wrapper only strips the
//! forwarded subcommand name and rebrands the top-level command, so there are
//! zero duplicated subcommand definitions.
