Non-terminal container output flows back to ctr via the shim's pipe mechanism. New files: - vxn-oci-runtime: OCI runtime (create/start/state/kill/delete/features/logs) - vxn-sendtty.c: SCM_RIGHTS helper for terminal mode PTY passing - containerd-shim-vxn-v2: PATH trick wrapper for runc shim coexistence - containerd-config-vxn.toml: CRI config (vxn default, runc fallback) - vctr: convenience wrapper injecting --runtime io.containerd.vxn.v2 Key design: - Monitor subprocess uses wait on xl console (not sleep-polling) for instant reaction when domain dies, then extracts output markers and writes to stdout (shim pipe -> containerd FIFO -> ctr client) - cmd_state checks monitor PID liveness (not domain status) to prevent premature cleanup race that killed monitor before output - cmd_delete always destroys remnant domains (no --force needed) - Coexists with runc: /usr/libexec/vxn/shim/runc symlink + PATH trick Verified: vctr run --rm, vctr run -d, vxn standalone, vxn daemon mode.
