SDK 0.3.1 — validated npm trusted publishing

Version-only packaging patch; SDK runtime and API contract unchanged from 0.3.0. Published through protected GitHub OIDC workflow https://github.com/SendHog/sdk-node/actions/runs/39512464718 with signed npm provenance (Sigstore log index 3345298421). npm trusted connection now reports Valid for SendHog/sdk-node, publish.yml, environment npm. No saved-token fallback. Canonical source: 66ca5e6cb5cfc931ba9edd0a115342abe002c362. Python, API and website unchanged.

SDK 0.3.0 — unified email webhooks

Published on npm as @sendhog/sdk@0.3.0. Adds email.received alongside bounce, delivery and other events in the same signed webhook contract. Existing subscriptions remain unchanged. Source provenance: b453c837ae78d077711ca5bcec57ebf95321a359. Artifact matches protected-CI validation exactly. GitHub OIDC upload failed because npm trusted publishing is not configured; the approved account published the same artifact with its existing SendHog-scoped credential. No OIDC provenance is claimed for this registry upload. Registry metadata and clean installation verified.
