Highlights:

• Lists now collect all element errors instead of stopping at the first one.
• Empty strings are treated as nil by integer, float, boolean, and atom types, making nilable and default behavior consistent across built-in types.
• Fixed error handling for malformed nested source paths and preserved full traces through nested unions.
• Expanded the documentation for defaults, validation, custom parsers, and error formatting.
