Re-renders hero.png without the baked-in stars (163k) and forks (25k) numbers
that were drifting from the README's own dynamic badges. Bottom stats now show
repo-derived catalog counts that don't rot: 310 total items (183 skills + 48
agents + 79 commands), 7 harnesses, ECC 2.0α, MIT.
Also shrinks the file from 534 KB to ~131 KB via tighter pngquant settings.
Addresses review comments from cubic and greptile (stat drift) and CodeRabbit
(file size).
