Anyquery: Path Traversal in `clear_plugin_cache` Allows Arbitrary Directory Deletion

Anyquery is an SQL query engine built on top of SQLite. Prior to 0.4.5, the clear_plugin_cache(plugin) SQL scalar function in namespace/other_functions.go passes the caller-controlled plugin parameter through path.Join to os.RemoveAll without rejecting traversal segments. A low-privileged bearer-token holder can invoke the function through the /v1/query HTTP endpoint, causing path.Join to resolve .. segments outside $XDG_CACHE_HOME/anyquery/plugins/ and os.RemoveAll to recursively delete any reachable directory writable by the Anyquery server process. This causes permanent data loss and denial of service without disclosing file contents. This issue is fixed in version 0.4.5.
