 Use SDK subpaths instead of the monolithic `openclaw/plugin-sdk` import when
 authoring plugins:

+- `openclaw/plugin-sdk/core` for generic plugin APIs, provider auth types, and shared helpers such as routing/session utilities and logger-backed runtimes.
 - `openclaw/plugin-sdk/compat` for bundled/internal plugin code that needs broader shared runtime helpers than `core`.
