Sydney RunkleandClaude Sonnet 4.6 b0a9ca7daa fix(channels): DeltaChannel subclass safety and order-independent Overwrite

copy() and from_checkpoint() hardcoded DeltaChannel instead of
self.__class__, breaking subclasses. Now mirrors the BinaryOperatorAggregate
pattern: self.__class__(self.operator) with explicit typ/key assignment.

update() applied non-overwrite values that arrived before an Overwrite in
the sequence, then discarded them when the Overwrite fired — order-dependent
behaviour in a method whose contract says order is arbitrary. Now pre-scans
for an Overwrite and applies only it (or folds all values normally if none).
