Interactive mode: ask user to retry with relaxed limits

[kyamagu]

When conversion fails due to resource limits in CLI, prompt user to retry:

Error: Layer depth 105 exceeds limit 100.

Would you like to retry with max_layer_depth=150? [y/N]: y
Retrying with relaxed limits...
Conversion successful!

Benefits

• Frictionless UX for users
• No need to remember environment variable syntax
• Can learn appropriate limits for specific files

Considerations

• Only for interactive CLI usage (not scripts)
• Need --no-interactive flag for CI/CD
• Security: careful with unlimited retries
• Should respect original environment variable settings
• May need confirmation for very large increases

Implementation Ideas

# In __main__.py
def main():
    try:
        convert(...)
    except ResourceLimitError as e:
        if sys.stdin.isatty():  # Interactive terminal
            suggested_limits = calculate_suggested_limits(e)
            if prompt_user_retry(suggested_limits):
                convert(..., resource_limits=suggested_limits)

Open Questions

• Should we remember user choices for this session?
• How many retry attempts before giving up?
• Should we suggest creating a config file for persistent settings?
