classfile,core: pick frame compact form by byte delta; honor --no-* flags

StackMapTable compact-vs-extended selection used the instruction delta,
but JVM validity requires the byte offset delta <= 63. Track byte offsets
in convert_frames and branch on byte_delta while keeping the instruction
delta stored (ristretto re-derives bytes).

Pipeline::run ignored config.disable, so --no-* CLI flags had no effect;
gate each pass on config.is_enabled.
