An actor lifecycle record went to stdout and to OTLP in two separate
calls. The attributes were shared, but the severity was not, so the slog
level sat at the call site and the OTel severity sat on the `Event`.
Nothing made a caller write both copies either, so a new record could
reach stdout only and no test would notice.
Since this PR `actorevent.Log` now writes both copies. The level comes
from `Event.Severity`, so it is stored once. The OTLP only `Emit` and
the exported body constants are gone, so the dual write is the only way
out of the package.
Also normalizes `ate.actor.operation.name` on the crash event, which the
state change event already did.
Fixes#1744
Testing
- Unit tests for the level mapping, the dual write, and the registry
check.
- End to end on a fresh kind cluster. Both event names arrive with the
right severity (9 and 17), the right attributes, and trace context on
the record fields. The stdout copies match record for record.
- [x] Tests pass
- [ ] Appropriate changes to documentation are included in the PR
