New Features ✨

• Add set_attribute, remove_attribute to global API by @sentrivana in #5555

  You can now set and unset attributes on logs and metrics via top-level API. Think of it as sentry_sdk.set_tag() for attribute-based telemetry. Other event types (transactions, spans, errors) will be unaffected.

  import sentry_sdk
  
  sentry_sdk.init(...)
  
  sentry_sdk.set_attribute("my.attribute", "my value")
  
  # This metric will have "my.attribute" set
  sentry_sdk.metrics.count("counter", 1)
  
  # Remove the attribute
  sentry_sdk.remove_attribute("my.attribute")
  
  # This log will not have "my.attribute" set
  sentry_sdk.logger.info("An info log")
