I'm curious about the definition with which you are familiar; how would you define deconstruction in contexts such as this one?
I'm using a definition that I've found to be common, although it may very well be incorrect. A fairly concise breakdown is given here, with expanded info on the "Analysis" tab below the title:
https://tvtropes.org/pmwiki/pmwiki.php/Main/Deconstruction
My understanding of this use of the term is that it goes a bit beyond mere subversion, by instead intentionally disregarding (rather than doing the opposite of) expectations and treating the elements of the trope as just stand-alone elements of a story . I.e., the girl is shy, but she isn't meant to be "the shy girl" and bring all the baggage that entails, rather, Hanako is a full character who just happens to have shyness as one trait amongst many.
I think the KS example is a little muddy because the authors were also intentionally trying to subvert, but they went beyond that by fleshing out her psychology and treating her behavior as more than just a twist. They wanted to (in my belief, again, I lack the grounding you mention) make a broader point about love-interest character psychology, not just surprise people with a bait-and-switch ending. For what it's worth, someone not familiar with the trope wouldn't feel subverted, because Hanako doesn't rely on the player having that familiarity in order to "correctly" engage with her or derive meaning from the route. If you are familiar, then you're at higher likelihood for being subverted, so in a way they accomplished both tasks without hindering either audience.
I would be happy to learn another, or more precise, use of the term. I also noted down what you said about the prologue, and I'll be sure to treat it as my cut-off.
