release: 2.5.1 — cosmokv CLI accepts bare paths

`cosmokv ./mydb` is now sqlite3-style shorthand for
`cosmokv 'DataSource=./mydb'`. The connection-string form still works
and remains the way to set options like `CreateIfMissing=true`.

-`<database>` is either a directory path (e.g. `./mydb`) or a CosmoKv connection string (`DataSource=./mydb;CreateIfMissing=true`).
+`<database>` is either a bare directory path (e.g. `./mydb` — `sqlite3`-style) or a full connection string (`DataSource=./mydb;CreateIfMissing=true`). The bare form is shorthand for `DataSource=<path>`; use the connection-string form when you need to set options like `CreateIfMissing=true`.
