herolib_ai on development past 3c2b35d0 (the ImageRef / image generation work, 633810f6 onwards) pulls a transitive image-io that dx 0.7.5 / krates 0.17.5 can't resolve. Every downstream WASM build via dx build panics:

internal error: entered unreachable code: unable to locate image-io for crate
  git+https://forge.ourworld.tf/lhumina_code/hero_lib.git?branch=development#herolib_ai@0.5.0
  features(["default", "usage"])

Current workaround in hero_os: [patch] block pointing at a local hero_lib checkout pinned at 3c2b35d0. Not portable.

Repro: check out hero_os, cargo update -p hero_archipelagos_messaging, dx build --package hero_os_app --web --features web --no-default-features.

Likely fix: feature-gate image-io behind a non-default feature in herolib_ai so WASM consumers that don't need image generation aren't forced to resolve it.
