doc-creation

Before creating a new .md file, check if the target directory is within a docs-manager library:

1. Run bash ${CLAUDE_PLUGIN_ROOT}/scripts/index-query.sh --search "$(dirname "$TARGET_PATH")" to check
2. If the directory is within a managed library:
   • Suggest: "This directory is part of the [library] documentation library. Use /docs new to create a managed document with proper frontmatter and index registration."
   • If the user declines, proceed with normal file creation
3. If not in a managed location: proceed normally without suggestion

This prevents untracked documents from accumulating in managed directories.
