Configuring a writable directory for the dsh-meow-memory memory plugin on Alibaba Cloud ECS

When running dsh web on Alibaba Cloud ECS with the seven-layer memory library plugin dsh-meow-memory (latest 0.31.0, 240★), you need a fixed mount point, ownership, working directory, and a systemd resident process to ensure the SQLite memory library is not lost after a restart. projectDir defaults to .dsh-meow relative to the current workspace; switching directories creates a new empty database without reporting an error, so you should fix WorkingDirectory or write an absolute path. The data disk must be written to fstab by UUID with nofail added, and the directory should be configured with chown -R dsh:dsh plus chmod 750 rather than 777.
