Correlate Sentry errors with OTel traces

[RhysSullivan]

Why

Sentry error events and the OTel traces exported to Axiom carried unrelated trace ids: Sentry mints its own trace context while the app owns a separate WebTracerProvider, so going from an error event to its request trace (or back) required manual timestamp and attribute joins during incident debugging.

Change

Minimal bidirectional tag join, no trace-context unification:

• Every outgoing Sentry event gets otel_trace_id and otel_span_id tags from the active OTel span (beforeSend for auto-captured errors, plus an Effect-aware capture helper for explicit captures).
• Explicit captures annotate the active OTel span with a sentry.event_id attribute for the reverse lookup.
• Scattered direct Sentry.captureException call sites migrated to the shared helper so they all carry the tags.
• DO-side captures stitch the worker-propagated trace parent, so session DO errors correlate too; paths with no active span leave the tags unset rather than inventing ids.

Full unification (Sentry adopting the OTel trace id as its own) was rejected: the app deliberately opts out of Sentry OTel mode and owns its tracer provider; Sentry Cloudflare OTel mode replaces the global provider and documents no support for custom context handling.

Verification

• Unit tests for the tagging helpers.
• New e2e scenario (env-gated synthetic error route, only mounted when SENTRY_OTEL_VERIFY=true in the e2e stack) asserting the captured event id, trace id, and span id match between the Sentry payload and the exported span.
• Typecheck, cloud build, format all green.
