You don't need an 'inclusive' definition. The reality is straightforward: a woman is an adult human female. As you already stated.

By contrast, a transwoman is a man who desires to be a woman, and perhaps also believes he is a woman, somehow. But he's not really a woman, and never can be, no matter how much he insists he is. Being male precludes this.

At most, he'll be a feminine man; a man performing femininity. Trying to mangle the definition of woman to include these men is ultimately fruitless, as it will be a lie.
