zerogpu: eager model load fixes consecutive-call crash; ghost dial 3/4 distinct

ghost: count-based monotonic dissolution so every dial level visibly differs

ghost: distance schedule [0,3,5,7.5,10] so multi-syllable words transform at high levels (fix dial-4 passthrough)

ghost quality: real-common-word filter (wordfreq) + dedup repeats + tighter phonetic distance
