v2.0.0

Full TypeScript modernization of eid.js.

New

• TypeScript with full type declarations (.d.ts)
• ESM + CommonJS + IIFE browser bundle

• tryToExecute preserves original error as .cause
• Vitest test suite (59 tests, 100% coverage)
• Biome lint/format
• GitHub Actions CI (Node 20 + 22)
• typecheck script (tsc --noEmit)

Fixed

• Off-by-one in checkElementIndex (index equal to size now correctly rejected)

Migration
