Macro tool_attribution 

macro_rules! tool_attribution {
    ($ty:ty, $kind:expr) => { ... };
}

Boilerplate-collapsing macro: pair a concrete Tool impl with a matching Attributable impl that surfaces the supplied ToolKind and uses the tool’s name() as its alias.

Invoke once per Tool struct, in the same module as the struct:

crate::tool_attribution!(ShellTool, ::zeroclaw_api::attribution::ToolKind::Shell);
