fix: update Event API for OpenTelemetry SDK 1.38.0 compatibility

Replace LogRecord with Event from opentelemetry._events to fix compatibility with OpenTelemetry SDK 1.38.0. The LogRecord API no longer supports event_name parameter; events are now emitted using the Event class with a name parameter. Changes: - Replace LogRecord import with Event from opentelemetry._events - Update event_emitter.py to create Event instances instead of LogRecord - Update test assertions to use event.name instead of event.event_name All 40 tests now passing. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
