Patch Changes

• #2738 89a3afb Thanks @gcanti! - add cause in errors thrown by asserts, closes #2729

• #2741 992c8e2 Thanks @gcanti! - Schema.optional: the default option now allows setting a default value for both the decoding phase and the default constructor. Previously, it only set the decoding default. Closes #2740.

  Example

  import { Schema } from "@effect/schema";
  
  const Product = Schema.Struct({
    name: Schema.String,
    price: Schema.NumberFromString,
    quantity: Schema.optional(Schema.NumberFromString, { default: () => 1 }),
  });
  
  // Applying defaults in the decoding phase
  console.log(
    Schema.decodeUnknownSync(Product)({ name: "Laptop", price: "999" }),
  ); // { name: 'Laptop', price: 999, quantity: 1 }
  console.log(
    Schema.decodeUnknownSync(Product)({
      name: "Laptop",
      price: "999",
      quantity: "2",
    }),
  ); // { name: 'Laptop', price: 999, quantity: 2 }
  
  // Applying defaults in the constructor
  console.log(Product.make({ name: "Laptop", price: 999 })); // { name: 'Laptop', price: 999, quantity: 1 }
  console.log(Product.make({ name: "Laptop", price: 999, quantity: 2 })); // { name: 'Laptop', price: 999, quantity: 2 }
