* feat(core): emit faas.instance span attribute for compute instance identity Synthesize a per-warm-instance id (cinst_<ulid>) once at module load and emit it as the OTEL faas.instance attribute on the flow and step route spans. Vercel exposes no native per-instance id under Fluid compute, so this lets traces distinguish which compute instance handled each request. Purely additive telemetry.

Emit a faas.instance OTEL span attribute (a synthesized per-warm-instance id) on the flow and step route spans, so traces can distinguish which compute instance handled each request.
