maaz519 0f923303d3 feat(p9): request-scoped trace context + middleware + structured logger
Task O.1: AsyncLocalStorage trace context (currentTraceId/runWithTrace/toTraceparent)
read by singleton services with no DI churn; Express traceMiddleware derives a trace
id per request (x-trace-id → traceparent → generated), echoes x-trace-id on the
response, runs the request in-context, and logs a structured http.request line on
finish. Minimal JSON structured logger stamps traceId on every line. Wired via
app.use in main.ts. 4 tests: scope, concurrency isolation, traceparent shape/parse.
