RPC Error Response Mapper (rpc/errors.ts)

Builds standardized RPC success/error envelopes and maps runtime, browser, and emulator errors to consistent, CLI-friendly error codes and messages.

// Why: every RPC response needs the same runtimeId envelope, and the
// runtime/browser error allowlists define the contract the CLI relies on to
// format human-facing messages. Centralizing this mapping keeps the allowlist
// auditable in one place instead of spread across per-method branches.
