ci: Notify linked issues on release

[buenaflor]

📜 Description

Add a release workflow that comments on GitHub issues closed by PRs included in a published stable release.

Also document that PR authors need to use GitHub closing keywords, such as Fixes #123, for linked issues to receive the release notification.

💡 Motivation and Context

This mirrors the release issue notification automation used by other Sentry SDK repositories and makes the required PR issue-linking behavior explicit for contributors.

💚 How did you test it?

Reviewed the workflow against this repo's release and changelog conventions. No automated tests were run because this is a GitHub Actions and documentation-only change.

📝 Checklist

• I reviewed submitted code
• I added tests to verify changes
• No new PII added or SDK only sends newly added PII if sendDefaultPii is enabled
• I updated the docs if needed
• All tests passing
• No breaking changes

🔮 Next steps

Monitor the first stable release run to confirm the action comments on issues linked through closing keywords.

Features

• (span-first) Add transaction and app start type span attributes by buenaflor in #3678
• Prevent cross-organization trace continuation by antonis in #3567
  • By default, the SDK now extracts the organization ID from the DSN (e.g. o123.ingest.sentry.io) and compares it with the sentry-org_id value in incoming baggage headers. When the two differ, the SDK starts a fresh trace instead of continuing the foreign one. This guards against accidentally linking traces across organizations.
  • New option strictTraceContinuation (default false): when enabled, both the SDK's org ID and the incoming baggage org ID must be present and match for a trace to be continued. Traces with a missing org ID on either side are rejected.
  • New option orgId: allows explicitly setting the organization ID for self-hosted and Relay setups where it cannot be extracted from the DSN.
  • Options are also applied to the native Android SDK. On iOS, only the Dart layer enforces strict trace continuation.
