docs: render architecture & flow diagrams as draw.io charts

Replace ASCII-art diagrams across the README and docs/ with editable .drawio sources plus exported PNGs, so the diagrams render clearly in rendered markdown and can be maintained/regenerated instead of being hand-edited as fragile text art. Non-diagram blocks (code, folder trees, UI wireframes) were left as text.

 T10 is the only task that requires all of T0–T9 done. Everything else can run in parallel.
