Assemble-changelog

Release-time changelog assembly for the Rerun repo.

Always work in the root of a standalone rerun-io/rerun checkout — normally the prepare-release-0.x.y branch, where the result is committed. This is step 4 of RELEASES.md; read it for the surrounding context.

Before doing any release work, verify that the current directory is the repository root and that its origin is rerun-io/rerun:

test "$(git rev-parse --show-toplevel)" = "$PWD"
git remote get-url origin

Do not run the workflow in the reality monorepo, including from its rerun/ directory. The release scripts need the standalone repository's 0.x.y tags and resolve (#N) commit references against rerun-io/rerun. Running them against reality can silently resolve reality PR numbers to unrelated Rerun PRs.
