Bug Fixes

WASM multi-module FuncRef resolution: FuncRef(id) is only unique within a module — per-module func_map snapshots prevent cross-module FuncId collisions that caused wrong function dispatch
WASM void function tracking: Functions returning void now push TAG_UNDEFINED after call for stack consistency
WASM optional parameter padding: Missing arguments padded with TAG_UNDEFINED for functions with optional params

obj[numericKey] on Record<number, T> — numeric keys converted to strings for property lookup
!('key' in obj) always returned false — in operator NaN-boxed boolean handling
trimStart()/trimEnd() dispatched to correct runtime functions
Cross-module default array parameter = [] SIGSEGV fix
IndexSet union-index NaN-boxing for closures on objects
.filter(Boolean) desugaring in all 4 HIR lowering paths
Null pointer guards in closure capture getters and Promise.all handlers
Cross-module await on Promise<[T, T]> tuple indexing
