Bug Fixes

• CI Visibility: This fix resolves performance issue affecting coverage collection for Python 3.12+

• LLM Observability: Resolves an issue where the langchain integration would incorrectly mark Azure OpenAI calls as duplicate llm operations even if the openai integration was enabled. The langchain integration will trace Azure OpenAI spans as workflow spans if there is an equivalent llm span from the openai integration.

• profiling: Upgrades echion to resolve an issue where stack profiler can allocate a large amount of memory unnecessarily. Resolves another issue where the profiler can loop infinitely on Python 3.13.
