The first CE channel's push-buffer was only pinned ~1 minute after the
client's failure: uvbp fired at t+4s but semfix's trace read (guest agent,
every 5 loops) picked it up at t+70s, so the tracker wait for value 3 spun
for 16 s. The guest scanner now emits '#pb 0x<kptr>' from the uvbp trace
lines as soon as they appear; the host mirrors them into the sem stream and
semfix resolves/pins the push-buffer through the UVM chain on the next loop
(sub-second).

queue 4k
- counter_pa autoreg result is written back to the channel table so later
passes cannot re-target a different slot when the live GR count changes
during teardown; re-registration of the same channel preserves the slot.
- counter slot layout uses the max GR count ever seen in the generation
instead of the shrinking live count.
- sema_map_add queue 64 -> 4096 entries so a full-window pin burst drains
without ENOSPC retries.
- pin_gr_stream: one batched sudo pass per flush (was one process per run,
~4 s for 400 runs), retrying only queue-rejected runs.
- semfix_uvmt: SEMFIX_SKIP_PB=1 skips the blocking push-buffer chain walk
when the vsock window stream already supplies those pages.

The guest-agent exec path is too slow under driver-init load (a 15k-page
window scan took 17-35 s to complete), so GR window pins landed after the
channels' entries had been consumed and after the client's cuCtxCreate
timeout. The guest now scans /proc/<pid>/pagemap locally and streams only
delta runs over vsock (no agent on the hot path); the host listener pins
them as they arrive. The scanner writes a pidfile so restarts do not kill
the new instance.
