After PR #21179 optimized `compute_new_claim()` to move polynomials instead of copying, the `virtual_size()` of accumulator polynomials no longer reliably reflects the accumulator's dyadic size. Use the explicit `dyadic_size` field which is always set correctly. This fixes WASM chonk integration tests that failed because `virtual_size()` returned 2^21 (CONST_FOLDING_LOG_N) causing CommitmentKey to request more CRS points than available.

…er (#21206) ## Summary - After #21179 optimized `compute_new_claim()` to move polynomials instead of copying, `virtual_size()` on accumulator polynomials no longer reliably equals the accumulator's dyadic size. - `HypernovaDeciderProver::construct_proof` used `virtual_size()` to create a `CommitmentKey`, which could request 2^21 CRS points — exceeding the WASM default of 2^20. - Fix: use `end_index()` to compute the tightest CRS size for the `CommitmentKey`, while passing `dyadic_size` to `PolynomialBatcher` and `ShpleminiProver` which need the multilinear domain size. ## Test plan - [x] `hypernova_tests` pass (9/9) - [x] `chonk_tests` pass (25/25) - [ ] CI chonk integration tests
