The extension's full behaviour now lives in dank/dankvoice (41/41
black-box suite against the built artifact; this branch's 26 drop-in
tests are a strict subset, names ported 1:1). Delete the drop-in and
its bats suite; repoint omp-docs/core/dankvoice.md at the package,
keeping only fleet wiring (frank-tts + @tiny resolution, the
enable_thinking hybrid law, voice/roster contract) and the cutover
procedure. kb-lint 0 violations; bats tests/ 45/45.
