Tianyi Cui a45bc8da67 fix(invariants): deepFreeze walks already-frozen objects' descendants ...

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.
