fix: surface the real NWListener error and drop conflicting requiredLocalEndpoint (#30)

The Local API failed to start with a generic "Could not start Local API on
port 47821" and no actionable cause. Two problems:

1. The NWListener construction catch discarded the caught error and
   substituted a generic string, so the real NWError was never surfaced or
   logged. Now the underlying error is logged via stateLogger (matching the
   .failed branch) and appended to the thrown message.

2. parameters.requiredLocalEndpoint pinned 127.0.0.1:<port> while the same
   port was passed as the listener's on: argument. Pinning a required local
   endpoint conflicts with the listener's own port assignment; acceptLocalOnly
   already constrains binding to the local link. Dropped requiredLocalEndpoint,
   keeping acceptLocalOnly + allowLocalEndpointReuse.
