PR Summary

Low Risk
Low risk dependency lockfile bump; behavioral impact should be minimal, but could affect JSON parsing edge cases and should be covered by the test suite.

Overview
Updates the locked json gem version in Gemfile.lock from 2.18.1 to 2.19.2 (dependency-only change). This pulls in upstream fixes including a security patch for JSON.parse(..., allow_duplicate_key: false).
