feat(plugin-sdk): export plugin hook types

Add `openclaw/plugin-sdk/types` entrypoint that re-exports plugin hook
types, so external plugins can import typed hook interfaces without
reaching into internal paths.

Also export `resolveActiveEmbeddedRunSessionId` from
`agent-harness-runtime` for session resolution in embedded runs.
