Subject: [PATCH] fix(doctor): close status-only memory manager after probe

The doctor.memory.status handler creates a memory manager with
purpose: "status" but never closes it. For qmd backends this opens
a read-only SQLite handle that only releases on close(), so repeated
health probes can accumulate file descriptors in long-lived gateway
processes. Add a finally block to ensure the manager is always closed
after the probe completes.
