PR Summary

Low Risk
Version and changelog-only release metadata; no runtime code changes in this diff.

Overview
This PR packages and publishes Commanded v3.8.0 by bumping the library version in mix.exs and .github/release-please-manifest.json, and adding the 3.8.0 section to CHANGELOG.md.

The release notes document what ships in this tag (not new code in this diff): W3C Baggage propagation via Commanded.Middleware.BaggagePropagator, router support for causation_id: nil to mark event-chain roots, a dispatcher fix so :causation_id is honoured on persisted events, and a handler fix so resets do not corrupt read models.
