• enable_logs is removed/is made no-op ⚙️
• enable_metrics is removed/is made no-op ⚙️
• sentry_sdk.logger.X and metrics APIs always work without any extra opt-in⚙️
• LoguruIntegration and LoggingIntegration both get a new integration level option (name TBD, maybe capture_sentry_logs?), default False ⚙️
  • in the integration, we'll capture logs as Sentry logs iff integration-level capture_sentry_logs is True ⚙️
• the existing sentry_logs_level logic/default applies as before — it's just gated behind the additional capture_sentry_logs option
