feat: ZeroSizeEngine + Make.com sync — Protocolo V10 Omega

[Copilot]

Implements the Linear Integration (Protocolo V10 Omega): biometric scan data → ZeroSizeEngine → Make.com webhook → Shopify/Instagram pipeline.

New modules

• src/lib/zeroSizeEngine.ts — ZeroSizeEngine class computing sovereign fit from scan data (chest, shoulder, waist, hip). Returns normalized ratios and a fit descriptor; raw measurements are never exposed in the result (Zero-Size Protocol).

• src/lib/makeIntegration.ts — syncSovereignty(scanData) drives the engine and POSTs the fit payload to Make.com via native fetch. Webhook URL resolved from VITE_MAKE_WEBHOOK_URL → MAKE_WEBHOOK_URL → MAKE_ESPEJO_WEBHOOK_URL.

const result = await syncSovereignty({ chest: 102, shoulder: 48, waist: 82 });
// result.fit → { torsoRatio, silhouetteIndex, fitDescriptor: "sovereign_fit", patente, protocol }
// Payload to Make: { patente, fit, timestamp, status: "Soberanía Confirmada" }

• tests/test_make_integration.py — 11 unit tests covering all fit descriptor branches, torso ratio calculation, waist/hip fallback, Zero-Size payload contract (no raw measurements), and ISO 8601 timestamp shape.
