fix: Split search / suggest results into an array?

[webbrain-one]

Closes #6

[greptile-apps]

Greptile Summary

This PR changes search and suggestion responses from scalar strings to arrays by splitting Sonic’s space-delimited result payloads.

• Applies array conversion to both Search#query and Search#suggest.
• Leaves the existing scalar-return specs and README examples inconsistent with the new API.

Confidence Score: 4/5

The return-type change should not merge until its failing scalar-return assertions and public API examples are updated.

Successful query and suggestion calls now return arrays, while the existing specs and documentation still enforce and advertise scalar results.

Files Needing Attention: lib/sonic/channels/search.rb, spec/sonic/channels/search_spec.rb, README.md

Important Files Changed

Filename	Overview

Array return breaks existing contract

When a query or suggestion succeeds, split changes the result from the scalar string required by the existing API assertions and examples into an array, causing those assertions to fail and callers following the documented contract to receive a different type.
