PR Summary

Low Risk
Single third-party version bump with no local code changes; typical low risk unless gson-fire 1.9.0 introduces serialization behavior changes at runtime.

Overview
Updates the json_fire_version Gradle property from 1.8.0 to 1.9.0, which drives the api dependency on io.gsonfire:gson-fire in build.gradle.

This is a dependency-only change with no application code edits; consumers of the SDK get the newer gson-fire release (including upstream Gson 2.10.1 and removal of internal Gson APIs).
