Subject: [PATCH] fix: build request URL via string concatenation instead of
 assigning to URL.search

Hermes (React Native) exposes URL.search as read-only, causing a runtime
error when assigning to it. This replaces the URL.search assignment in
eventSource() and getResponse() with string-based URL construction,
ensuring compatibility across all JavaScript runtimes.
