test: 16 dynamic PRG tests — all new syntax works in FRB/runtime
Verifies every Five extension works in dynamic compilation: - Multi-return (RETURN a,b + a,b := Func()) - DEFER (Go defer in PRG) - Slice (a[2:4]) - Channel operators (ch <- val, <- ch) - SPAWN / LAUNCH / GOROUTINE - WATCH (channel multiplexing) - ASYNC / AWAIT - WITH TIMEOUT - Nil-safe (?:) - f-string interpolation - CONST block - PARALLEL FOR - IMPORT + pkg.Func() (Go direct call) - obj:Method() (Go object bridge) - MacroEval (runtime expression evaluation) All 16 tests PASS — dynamic PRG has full feature parity.
