fix(signals): a guess derived from another hold's live guess entangles the two (#4788) (#4798)

* fix(signals): a guess derived from another hold's live guess entangles the two (#4788)

An action's imperative reads of a guess (its body, a createOptimistic
setter, a store setter's draft keys a live guess wrote) are noted until
the seam; a guess written at that seam merges its frame with theirs, as
same-slot writes do (D-33, ruled 2026-11-12). Navigation through a
guessed index, the keyed diff of a returned array, and reactive readers
note nothing; a read alone entangles nothing.
