otel_shelf 0.1.0

OpenTelemetry instrumentation for `package:shelf`. Middleware that opens a SERVER span per request, extracts the inbound W3C traceparent and records `http.*` semconv attributes.

Changelog

0.1.0 - 2026-08-10

Added

• otelShelfMiddleware({tracer, errorStatusBuilder}) — a shelf Middleware that opens a SERVER span per incoming request with http.request.method, url.full, server.address, server.port, http.response.status_code.
• Extracts the W3C traceparent header from inbound requests so the device/CLI client's trace stitches into this server span.
• 5xx flips span status to Error by default; 4xx does not (per OTel HTTP semconv — 4xx is client-side error). Override via errorStatusBuilder.
• Zone-scoped suppression (runWithoutShelfInstrumentation / async variant).
• 4 tests including end-to-end traceparent stitching.
