core: add async reverse lookup contract

- add a typed reverse-lookup result alias to the shared location resolver boundary
- add backend hooks to begin and poll reverse location lookups without blocking the ui thread
- keep the existing synchronous resolver methods available for non-ui call sites during the transition
- preserve current runtime behavior until the platform backends and home lookup ui switch to the new contract
