Clean project references and separate optional bench tooling

Remove unrelated ecosystem comparisons and software citations while retaining hardware links, measured model names, and required license notices.

Preserve stock-peer runners and tests in a verified local validation package. Keep shared Companion USB transport in the firmware repository for the raw-radio sweep and OTA seeder, with focused CI coverage. Restore missing hosted documentation links.
