Meysam Parvizi 4c52895477 feat(site): use curated connections between topics
Connections come from the links list in map.json instead of only from shared or mentioned resources. Curated ones are solid lines with a reason in the details panel; the text-based ones stay as faint dashed evidence. Tests check names, duplicates and that every technical topic is connected.
