feat: add an optional effect map to createStore (RD-05)

Browse Source 
createStore now takes a third, optional StoreEffects map. Each key is a
Model tag. The store runs that tag's handler after update() returns, and
only when the store enters the tag: the previous tag differs from the new
tag, and the message is not Seed (the mount/restore message in every
machine that has one).

This closes the gap where a component had to call dispatch(msg) and then
a private runIfSubmitting() by hand, or state got silently stuck. No call
site changes here. RD-06 and RD-08 migrate the 5 components that
duplicate that pattern today.

The effect map is a conditional type, not a generic constraint, so a
tagless Model (store.spec.ts's plain number store) still resolves it to
never and needs no third argument. Both tag checks use a typeof/in guard
for the same reason.

Regenerated libs/shared/docs/behaviour-spec.mdx for the 5 new spec titles.
