Replace the separate (nodes, params) fields on the Dealer/Receiver structs with a single validated ShareConfig, and route the scattered derived-quantity computations through its getters: - ShareConfig is now Arc-backed and hands the shared node set to Avid via nodes_arc(), preserving the single-allocation sharing. - batch_avss_avid's t+f vote quorum now uses config.certificate_quorum().
- sharing_degree() (t-1) replaces the hand-rolled polynomial-degree arithmetic in avss (sampling and the feldman-commitment degree check). - has_reconstruction_threshold(ids) folds the 'total weight of a subset >= t' check used by both avss::Receiver::recover and batch_avss_avid; callers keep their own error type.
