docs(scripts): add molecule workflow note to bump-version.sh

Document that version bumps should be done via molecule bonding for
guided, resumable releases. The bd-6s61 template creates child beads
for each release step.

Until bd mol bond is implemented (bd-usro), use bd template instantiate.

+# MOLECULE WORKFLOW (Recommended)
+# =============================================================================
+#
+# This script handles the mechanical version updates, but the full release
+# workflow is captured as a molecule. For guided, resumable releases:
+#
+#   bd template instantiate bd-6s61 --var version=X.Y.Z --assignee <identity>
+#
+# This creates child beads for each release step. The molecule survives
+# session restarts - any agent can pick up where another left off.
+#
+# The molecule (bd-6s61 "Version Bump: {{version}}") includes:
+#   1. Update CHANGELOG.md and info.go
+#   2. Run this script (bump-version.sh)
+#   3. Run tests and linting
+#   4. Commit, tag, push
+#   5. Update Homebrew formula
+#   6. Verify installation
+#
+# Until bd mol bond is implemented (bd-usro), use bd molecule instantiate.
