ph telemetry

Vendor-neutral tracing abstraction. Provides a thin span API plus a ServiceLoader-based SPI for plugging in a concrete backend (OpenTelemetry, Jaeger, Zipkin, etc.). If no implementation is registered, a built-in no-op tracer is used so callers can write tracing code unconditionally.

Highlights:

• Telemetry - static facade for starting spans; lazily resolves the SPI implementation and falls back to a no-op tracer when none is registered
• ITelemetrySpan - fluent span API with typed attribute setters, exception recording, and OK/ERROR status
• ITelemetryTracerSPI - SPI interface to be implemented and registered via META-INF/services by a backend module
• ETelemetrySpanKind - mirrors OpenTelemetry's SpanKind (INTERNAL, CLIENT, SERVER, PRODUCER, CONSUMER)
• Telemetry.withSpan (name, kind, body) - convenience that starts a span, records exceptions on it, and ends it in a finally block
