Detailed Description
A directed coupling between Forma participants.
A Link has two distinct moments:
establish - runs once at construction. This is where the coupling is formed: attaching a processor to a buffer, setting initial state, registering a relation. For some links this is the entire effect.
activate - the repeatable body of the coupling. Closed over whatever source and target participants are relevant. Expresses the full transfer: read, transform, apply, any gating. When the link has no repeatable behavior, activate is []{}. It is always callable.
Who calls activate and when is entirely the caller's concern. A Context callback, a version-gating wrapper, a Lila script, another Link's activate body - all are valid drivers.
