bridge: skip Ozone 11 modules (license fastfail c0000409 kills scan/render)

Ozone 11 (iZotope) tu __fastfail FATAL_APP_EXIT khi load — khong bi SEH chan,
giet ca bridge process. Scan -> mat ca dir -> FX list rong; render/realtime ->
crash. Khong load: scan emit UNKNOWN, load tra loi sach. Ozone Pro van OK.
ponytail: SandboxVst3Host (1 module 1 process) khi can Ozone 11.
