"""Conversation scanners — backwards-compatible re-exports.

Concrete scanner implementations have moved to headroom.learn.plugins.*.
This module re-exports them so existing imports continue to work:

    from headroom.learn.scanner import ClaudeCodeScanner  # still works
    from headroom.learn.scanner import is_error_content    # still works
