Deactivation now clears the endpoint-check transient and the cached rewrite rules (forcing WordPress to regenerate them without this plugin's routes on the next request) and activation asks mcp-oauth to re-flush its own rules. uninstall.php removes all own options/transient/cron/table across every site of a network, delegating to the new self-contained LIT\MCP\Uninstaller class so it works without the plugin's autoloader and is unit-testable on its own. mcp-oauth's data (JWT secret, rewrite marker, refresh-token meta, application passwords) is left untouched, as is every post/attachment/revision.
