[Bug] Claude Code hangs when resuming certain conversations with large tool outputs in history

Bug Description
When resuming a session that contains a large tool output (e.g., a 1.4MB git diff or file read), Claude Code
freezes/hangs while attempting to render the session history in the terminal

Steps to Reproduce

1. Start a Claude Code session
2. Run a command that produces large output (e.g., git diff on many files, reading a large file)
3. Exit the session
4. Try to resume the session using /resume or the resume picker
