bump affinescript: fix enum-in-match + param struct-field codegen

Pulls in affinescript 35c476d which fixes two WASM codegen bugs
discovered 2026-04-19 in the double-track-browser lifecycle pilot:
(1) PatCon-with-args stack imbalance that made any match arm body
producing an i32 fail WASM validation, and (2) non-first struct-field
reads from function parameters silently returning 0.
