[Bug] Agent stuck in infinite thinking state consuming tokens without output

Bug Description
'm experiencing a recurring bug in Claude Code where the agent gets stuck in an extended "thinking" state indefinitely — the token/usage counter keeps climbing but no output or tool calls are produced. This has happened across multiple separate sessions, so it's not isolated to one conversation or project. The only way to stop it is to manually press Escape/Ctrl+C, by which point a significant amount of my usage/tokens has already been consumed for nothing.
