ReactiveNode class

A node in the reactive dependency graph.

Anything that participates in reactivity — a value source (signal-like), a derived value (computed-like) or a side effect (effect-like) — is a ReactiveNode. A node keeps two intrusive doubly-linked lists:

• deps/depsTail: the nodes it reads from (its dependencies);
• subs/subsTail: the nodes that read it (its subscribers).

Each edge between two nodes is one ReactiveLink, shared by both lists. This gives O(1) insertion/removal with zero hashing and zero snapshot allocation during propagation.

Um nó no grafo reativo de dependências.

Tudo que participa da reatividade — uma fonte de valor (tipo signal), um valor derivado (tipo computed) ou um efeito colateral (tipo effect) — é um ReactiveNode. Um nó mantém duas listas duplamente ligadas intrusivas:

• deps/depsTail: os nós que ele lê (suas dependências);
• subs/subsTail: os nós que o leem (seus subscribers).

Cada aresta entre dois nós é um único ReactiveLink, compartilhado pelas duas listas. Isso dá inserção/remoção O(1) sem hashing e sem alocação de snapshot durante a propagação.
