docs: principe — le polyfill compense, il n'étend jamais

Règle posée par l'utilisateur : la seule raison d'être du polyfill est de combler
un retard d'implémentation NextGraph ou un bug. Aucune fonctionnalité additionnelle
propre (pas de feature, d'observabilité, d'API de confort qui ne soit pas « NextGraph
le fera nativement plus tard »). Corollaire : une compensation dont le gap n'est PAS
exhibé sur le broker cible est du poids mort, pas du code défensif — à retirer.

## Principle — the polyfill compensates, it never extends
**The polyfill's ONLY reason to exist is to bridge a NextGraph implementation gap
or a bug.** Every non-SDK surface must map to a capability NextGraph will provide
natively, and must fall away at that point. The polyfill MUST NOT add functionality
of its own — no bespoke features, no observability/tooling, no convenience API that
isn't strictly "NextGraph will do this natively later." The test for any proposed
addition: *does it compensate a real, exhibited NextGraph gap or bug?* If not, it
does not belong here — build it in the consumer application, not in the polyfill.
Corollary: a compensation whose gap is not actually exhibited on the target broker
is dead weight, not defensive code — it should be removed, not kept "just in case."
