HyperEVM

Creates one or more sub-accounts under an affiliate at deterministic addresses, each scoped to a specific Symmio core and isolation strategy.

Each entry in `accountsData` produces one sub-account whose address derives from the affiliate, the caller, and a global nonce. The supplied `symmioCore` must be both whitelisted and registered for the affiliate, the affiliate must be `ACTIVE`, and `singleVAMode` is only legal with `MARKET` or `MARKET_DIRECTION` isolation. The affiliate's `onAccountCreation` hook fires for each sub-account once it is recorded.
