Implement full snapshot lifecycle: pause (snapshot + free resources), resume (UFFD-based lazy restore), and named snapshot templates that can spawn new sandboxes from frozen VM state. Key changes: - Snapshot header system with generational diff mapping (inspired by e2b) - UFFD server for lazy page fault handling during snapshot restore - Stable rootfs symlink path (/tmp/fc-vm/) for snapshot compatibility - Templates DB table and CRUD API endpoints (POST/GET/DELETE /v1/snapshots) - CreateSnapshot/DeleteSnapshot RPCs in hostagent proto - Reconciler excludes paused sandboxes (expected absent from host agent) - Snapshot templates lock vcpus/memory to baked-in values - Proper cleanup of uffd sockets and pause snapshot files on destroy
