The build system v2 guide now references these examples with :example:
and :example_file: roles, so check_examples_documented.py no longer
expects them in the KNOWN_MISSING list. component_manager and the nested
import_prebuilt/prebuilt project are kept, since the guide does not link
them.

Replace the peripherals index USB entries with direct links to
ESP-USB so the generated pages are no longer redirect-only stubs.
Keep legacy USB URLs working via redirects, including the
individual USB host maintainer notes pages.
Remove the obsolete placeholder documents and stale CODEOWNERS
pattern.
Mark the moved USB examples as KNOWN_MISSING in the example
documentation checker until it can also read the ESP-USB guide.
