Rename to Kotej and add the app icon

"Cotejo" means nothing outside Spanish and is hard to pronounce elsewhere, so the
project is now Kotej: same root, but it reads and sounds the same in English and
Spanish. Renamed throughout — engine, targets, bundle ids and the URL scheme,
which is now kotej://compare.

Icon generated with Codex: two facing panels split by a seam, content lines on
each side and one amber line marking a difference — the tool's job at a glance,
still legible at 16pt.

34 tests still green; kotej:// verified end to end against the demo JARs.
