// Tests in this file enable the real SDK (initSentry(true) / withTelemetry with
// SENTRY_CLI_NO_TELEMETRY unset), which uses the production SENTRY_CLI_DSN. The
// transport sends via node:http/https, bypassing the global fetch mock in
// preload.ts, so without this stub every captured test fixture (e.g. CLI-299)
// is uploaded to the real CLI Sentry project. Replace it with a no-op transport
// so the full capture pipeline still runs but nothing leaves the process.

// Snapshot beforeExit listeners before any test calls initSentry(true).
// The ProcessSession integration registers an anonymous handler via setupOnce
// that has no cleanup mechanism. After all tests, we remove any listeners
