Preserve incoming traceparent in verbose-mode spans by extracting request context pre-handler

Preserve incoming traceparent in verbose-mode spans by extracting request context pre-handler targets a $20.0B = 2M organizations x $10K/year (average spend on observability & developer telemetry tooling) total addressable market with medium saturation and a year-over-year growth rate of 15%.

Key trends driving demand: Standardization on OpenTelemetry -- reduces vendor lock-in and increases demand for correct OTEL integrations across frameworks; Serverless & edge compute -- increases surface area for context propagation errors, making instrumentation correctness more valuable; Observability-in-the-Framework -- frameworks shipping first-class telemetry hooks (Next.js, Deno, etc.) create opportunities for tight integrations; SRE and SLO focus -- teams demand reliable distributed traces for incident response and root-cause analysis.
