vgsp: eng43 - keep the MME pack completion record and packed cursor across an owner channel re-register (sema_gl_mme_keep_done_across_recycle, default 0)

c579: the first eng42-module completion (2799/2799) was followed 1.09 s later
by the beef owner re-register; the eng40 chan_ctx_reset treated the recycle
as a context loss, rewound the pack cursor and wiped pack_done_gen/ch, so
every later prelude launch re-emitted (pre_words_out > 0 -> the r1222 clause
correctly withheld the release) and MME-PACK-REARM could never fire.

The knob keeps pack_done_h/gen/ch and the cursor (pack_off/pack_sa/load
accounting) across the re-register so the first prelude launch on the
re-incarnated channel is non-emitting and the REARM clause releases the held
calls against the engine-resident program. The per-incarnation
latch/live/release state is still cleared, and every genuine context wipe
(WEDGE-RECOVER/CWD-CLEAR, park recovery, iram-gate failure, non-keep_gen
generation rewind, FLR via reload) clears the record on its own path.
Default 0 = legacy invalidate (validation pending).
