v0.3.0

The es2026 edition lands on both specs.

Added

• ECMA-262 and ECMA-402 add the es2026 edition. Both specs now
  cover es2016 – es2026 plus main. tc39/ecma262 tags es2026;
  tc39/ecma402 publishes it as an esYYYY branch. clause.get,
  spec.search, spec.diff, spec.history, and the rest of the
  edition-aware surface resolve es2026 on both specs.

Changed

• latest now resolves to es2026 on both ECMA-262 and ECMA-402
  (previously es2025). main / draft / next continue to address
  the working draft.
• The npm bundle tracks the new stable. The offline fallback now
  ships spec-262-es2026 + spec-402-es2026 (replacing the es2025
  pair); every other edition is fetched from the hosted Worker on
  demand.
