vgsp-sema: host-triggered VAS pdb discovery (sema_pdb_discover va,pa -> verify the parked COPY_SERVER_PDES candidates against a content-verified ring pair, then fall back to the vidmem walk-root sweep) + runtime-tunable candidate age-out (sema_vas_cand_ms; the default 15 s ages the client's VAS candidate out exactly when its channels first register, so the verified walk can never anchor it by itself)
