agent: observability

When does this happen?

IF Using arize-phoenix-otel v0.10.0 with register() and multiple span processors (e.g., one simple and one batch) causes UnboundLocalError in _tracing_details when verbose=True or auto_instrument=True is set.

How others solved it

THEN Upgrade to v0.10.1 or later, which fixes the regression. If unable to upgrade, ensure only one span processor is added or avoid calling register with verbose=True until the fix is applied.
