Release v202611-00009

On x86_64 the dynamic loader lives in /lib64, so the probe failed with
"execvp /bin/true: No such file or directory" and shell commands of non-admin
users were disabled on amd64 hosts. The sandbox itself already mounted it.

+## [v202611-00009] – 2026-11-09
+
+### Fixed
+
+- **Sandbox on x86_64:** the start-up check of bubblewrap did not mount `/lib64`, so it failed
+  on amd64 hosts and shell commands of non-admin users were disabled.

+# Roll out a published CodeCraft image to a remote installation that was set up with
+# scripts/move-server.sh (docker-compose.yml + .env in one folder on the target).
+#
+#   scripts/release.sh        # build and publish a new version (amd64 + arm64)
+#   scripts/deploy.sh         # roll the newest tag out to the target
+#
+# Steps:
+#   1. check that the image exists in the registry for the target's architecture,
+#   2. wait until no agent or terminal runs on the target (unless --force),
+#   3. set CODECRAFT_VERSION in the target's .env, docker compose pull && up -d
+#      (or start.sh on hosts without Compose),
+#   4. run scripts/smoke-test.sh on the target; on failure the previous version is
+#      started again.
+#
+# Usage: scripts/deploy.sh [vYYYYMM-NNNNN] [--target user@host:/dir] [--force]
+#                          [--wait MINUTES] [--dry-run]
+#   vYYYYMM-NNNNN   version to deploy (default: the newest vYYYYMM-NNNNN git tag)
+#   --target        installation folder on the target (default: DEPLOY_TARGET from .env)
+#   --force         restart even if agents or terminals are running (they end)
+#   --wait N        how long to wait for an idle server before giving up (default 15)
+#   --dry-run       show the steps only
+#
+# Environment:
+#   REGISTRY        image name without tag (default git.familie-zink.org/zink/codecraft)
+#   CONTAINER       container name on the target (default codecraft)
+#   PORT            port of CodeCraft on the target, for the smoke test (default: PORT
