Release 0.4.1: Jinja2 templates render forms without |safe

SafeHTML.__html__() is a method returning the HTML string,
satisfying MarkupSafe's escape() protocol. Jinja2 auto-escaping
recognizes form.render() output as trusted HTML.

+## AirForm 0.4.1: Fix __html__ for Jinja2 compatibility
+
+`SafeHTML.__html__` is now a method that returns the HTML string, not a boolean attribute. Jinja2 and MarkupSafe call `obj.__html__()` and expect a string back. The 0.4.0 release had `__html__ = True`, which raised `TypeError: 'bool' object is not callable` when Jinja2 tried to auto-escape form output.
+
+```sh
+uv add AirForm --upgrade
+```
+
+### What's fixed
+
+- **`{{ form.render() }}` works in Jinja2 templates without `|safe`.** MarkupSafe's `escape()` calls `obj.__html__()` to get trusted HTML. The method returns `str(self)`, satisfying both Jinja2/MarkupSafe (calls it) and Air's tag system (checks `hasattr`).
