+#   3. Bumps the workspace version across Cargo.toml (workspace.package and

+#   4. Runs `cargo check --workspace` to confirm the bump compiles.
+#   5. Commits as "release: vX.Y.Z" and pushes `dev`.
+#   6. Opens a PR `dev` -> `main`.
+#
+# After merging the PR, the Release workflow on `main` tags, publishes to

+# Requires: cargo-edit (`cargo install cargo-edit`), gh CLI authenticated.
