last release VA; larger push log budget

The first deltas of a 15k-page window took tens of seconds to arrive while
the client was mapping under load, so the pins still landed after the
client's cuCtxCreate deadline. The scanner now reads only the first 64 KB
of every 2 MB region - the pushes sit at the per-channel allocation heads -
which cuts the per-loop page-table work ~50x, and it logs scan timing so
the latency stays visible.

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.
