chore: pick up nearest-config polyfill fix

Polyfill previously selected the first config filename found while walking
up, so mixed dagger.json and dagger-module.toml layouts could resolve to the
farther module based on filename order.

Pin the merged dagger/polyfill#4 revision for shared module discovery. The
explicit mod lookup continues to perform its own nearest-config validation;
the shared modules path now has the same behavior without another workaround.
