Daniel e69eb9a9f7 fix: modifying a presentation failed whenever illustration was ticked ... existingDeck was declared below the branch that reads it, so `var` hoisting made it undefined there. With illustration on, a deck modification therefore appended the *markdown* instruction — "Returning the markdown is still required; a tool call is not a substitute for it" — to a prompt whose body asked for deck JSON. The model was told to produce two different artifacts in one reply, the reply parsed as neither, and deckBuild.parse returned null, so the handler answered 502 "That change could not be applied." Moved the declaration above its first reader. Same class of fault as the savedFigureIds one, in the same file. Two things made it hard to see, both fixed: - The library row read created_at, so a modification that did apply left the visible timestamp on the generation time. That timestamp is what led to "modification doesn't work" — it was the only signal available, and it was reading the wrong column. Rows now show the modified time when there is one. - A model can also return the document back unchanged. That was logged server-side and answered "Applied. Download it to see the result", which sent people to download an identical file. The response now carries `unchanged` and the UI says so, keeping the instruction in the box so it can be reworded. Also surfaced has_deck on the library list: 28 of 38 stored presentations have no deck and go through the weaker flat-markdown path, and nothing in the UI distinguished them. They now read "plain text, no slide layout". test/my-resources-refine.test.js runs the handler rather than reading it, since all three faults were invisible to source reading. Verified against a mutation: putting the declaration back where it was fails test 1 and nothing else.
