fix: improve chat adapter reliability - prevent hangs and use all relay hints

- Add error and complete handlers to prevent subscription hangs
- Merge relay hints from both identifier.relays and identifier.value.relays
- Ensures events can be found even with limited relay availability
- Fixes 'expects kind 1 not 1111' errors by using all available relay hints
