Session.append accepts event data from arbitrary plugins/tools, so a caller can pass a SHALLOW-frozen object with mutable descendants. The old Object.isFrozen early-return skipped such an object entirely, leaving its descendants mutable in the log — exactly the history mutation ADR 0012 means to catch. Now always descend, tracking visited objects in a WeakSet for cycle-termination and idempotence. Addresses PR review finding.
