Pull request overview

This PR fixes initialization logic in the observability core module and prevents direct instantiation of the Agent365Exporter by marking it as an internal class. The key changes ensure that all span processors are properly added to the tracer provider and that the exporter is only accessible through the configuration API.

Key Changes:

• Fixed initialization logic to properly add both BatchSpanProcessor and SpanProcessor to the tracer provider
• Renamed Agent365Exporter to _Agent365Exporter with @final decorator to indicate it's internal
• Added duplicate initialization prevention in the configure function

• The docstring for this class should be updated to indicate that this is an internal/private class that should not be instantiated directly by developers. Consider adding a note like "Note: This is an internal class. Use the configure() function from the observability.core module instead of instantiating this class directly."
