• Bump gotenberg version 8.27.0 -> 8.29.0.
• Add support for --chromium-idle-shutdown-timeout and --libreoffice-idle-shutdown-timeout flags to automatically shut down idle browser/office processes.
• Add support for API telemetry control flags: --api-disable-root-route-telemetry, --api-disable-debug-route-telemetry, --api-disable-version-route-telemetry.
• Add support for new PDF engine flags: --pdfengines-watermark-engines, --pdfengines-stamp-engines, --pdfengines-rotate-engines, --pdfengines-read-bookmarks-engines, --pdfengines-write-bookmarks-engines.
• Rename api.traceHeader to api.correlationIdHeader (--api-correlation-id-header). The old key still works for backward compatibility.
• Rename api.disableHealthCheckLogging to api.disableHealthCheckRouteTelemetry (--api-disable-health-check-route-telemetry). The old key still works.
• Rename logging.format to logging.stdFormat (--log-std-format). The old key still works.
• Rename logging.enableGcpFields to logging.stdEnableGcpFields (--log-std-enable-gcp-fields). The old key still works.
• Rename prometheus.disableRouterLogging to prometheus.disableRouteTelemetry (--prometheus-disable-route-telemetry). The old key still works.
• Breaking upstream change: Health check route telemetry is now disabled by default in Gotenberg 8.29.0 (previously enabled). This applies even without passing the flag.
• Document OpenTelemetry support via standard OTEL_* environment variables through extraEnv.
