📝 Walkthrough

The change adds reusable span configuration and callback execution methods. Do and Do2 start and end spans, set status based on callback results, and record panics. Tests cover results, context propagation, configuration, reuse, and termination paths.

Changes: Span configuration and execution

Layer / File(s)	Summary
Span configuration pkg/framework/tracex/v2/span.go, pkg/framework/tracex/v2/span_test.go	Adds SpanOption, WithOkStatusDescription, NewSpan, and WithOption. Tests check option composition and that deriving a configuration does not mutate its source.
Callback execution and span completion pkg/framework/tracex/v2/span.go, pkg/framework/tracex/v2/span_test.go	Adds Do and Do2 to run callbacks with a span context, record callback errors, set status, and end spans. Tests cover success, errors, cancellation, deadlines, panic propagation, reuse, and runtime.Goexit.

- Around line 109-113: Update NewSpan to copy the opts slice when constructing
Span, so later caller replacements cannot affect the stored start options used
by Do, Do2, or derived configurations created with WithOption.
