refactor(iii): replace dynamic require with static import for SDK_VERSION

[Copilot]

iii.ts was loading the package version at runtime via createRequire, which is unnecessary given resolveJsonModule: true is already set in tsconfig.json.

Changes

• src/iii.ts: Swap dynamic createRequire-based version load for a static ES import:

// Before
import { createRequire } from 'node:module'
const require = createRequire(import.meta.url)
const { version: SDK_VERSION } = require('../package.json')

// After
import { version as SDK_VERSION } from '../package.json'
