Module catalog 

Canonical hardware tool-name and capability catalog.

Single source of truth for the names the agent sees and the docs render. fn name() impls and the mdBook hardware snippets both read these constants so a rename lands in one place and the rendered tables follow on the next docs build. Non-gated so xtask can walk it without the hardware feature.

Constants

AARDVARK_TOOLS

Tools loaded only when at least one Aardvark adapter is present at boot.

BASE_TOOLS

Built-in hardware tools always present with the hardware feature.

PROBE_TOOLS

probe-rs backed introspection tools (in zeroclaw-tools).
