/// Macro for defining the command execution pipeline.
///
/// Generates `execute_command(step, cx)` — matches `StepKind` variants and
/// calls the corresponding handler. `lower_command` and `all_metadata` are
/// generated by `declare_commands!` in `oxdock-parser/src/commands.rs`.
///
/// Each entry specifies a pattern (`$pat`) and a handler function with
/// signature `fn(&StepKind, &mut StepCtx<'_, P>) -> Result<()>`.
