Description

Asana task

Recreates the partner PR with no changes found to be needed:

• feat: add sui to rango #438 — feat: add sui to rango

---

Note

Low Risk
Mapping-only change with no swap logic or auth changes; same pattern as prior Rango chain additions like SUI.

Overview
Enables Sonic on the Rango DEX aggregator by wiring Rango’s SONIC network to Edge’s sonic plugin in both mapping directions.

scripts/mappings/rangoMappings.ts changes SONIC from null to 'sonic', and the generated src/mappings/rango.ts maps sonic → SONIC (was null). The unreleased CHANGELOG notes “(Rango) Sonic support.”

Looks good, my only feedback is about the provided test evidence. Ideally, we test both directions but if I had to choose one it's more appropriate to test selling the new asset since it will go through the more complicated transaction creation flow. Parse the swap partners address, calculate fees, etc.
