Adds a concise guide to `docs/release-process.md` explaining how the
release workflows interact, with focus on the version semantics that
differ between minor and patch bumps.
Key sections:
- How minor bumps freeze the previous minor into `core/` and `cloud/`
branches
- How patch bumps on `main` vs `core/X.Y` differ (published vs draft
releases)
- Why unreleased commits are dual-homed when a minor bump happens
- Summary table, backporting, publishing, and bi-weekly automation
