The v0.1.0 arm64 image passed every gate in docker.yml (the MCP smoke, the in-container orlyc compile, the REPL check) while segfaulting just after the first write through a POV (#578). Each of those smokes stops looking as soon as its write answers, and the crash landed a moment later.

This adds one step after the MCP smoke. It writes through all four POV flavours (safe/fast × shared/private), five fresh POVs each, waits 5s, and requires docker inspect to report running exit=0 restarts=0. It runs on both arches, on PRs that touch the image and on every publish.

Verified locally against the published images (native arm64)

image result
v0.1.0 connection lost mid-loop, container exited exit=139, so the step fails
v0.1.1 20 writes answered, container running exit=0 restarts=0, so the step passes

The step runs after the MCP smoke, which has already installed sample. The local test installed it first too, to make sure the second install doesn't error.

This PR touches docker.yml, so its own CI builds both images and runs the new step on each.

…ur (#578)

The v0.1.0 arm64 image passed the MCP smoke, the in-container orlyc
compile and the REPL check while segfaulting just after the first write
through a POV. Each of those smokes stops looking as soon as its write
answers, and #578's crash landed a moment later.

After the MCP smoke, write through safe/fast x shared/private, five fresh
POVs each, wait five seconds, and require the container to still be
running with exit 0 and no restarts.

Checked locally against the published images: v0.1.0 arm64 dies under
the step (exit 139); v0.1.1 arm64 answers all 20 writes and stays up.
