[Bug] Claude Code hangs with stagnant token usage until retry

Bug Description
Claude Code keeps hanging. It shows that it's working (time elapses), but token usage stays stagnant and will hang until I retry the request. Frustrating.

For instance:
Finagling… (1m 42s · ↓ 3.0k tokens)


It won't continue. Just stays there, as the time elapses. Predominantly experiencing this on Opus 4.6
