* Normalizes a model name by extracting the filename from a path, but preserves Hugging Face repository format.
*
* Handles both forward slashes (/) and backslashes (\) as path separators.
* - If the model name has exactly one slash (org/model format), preserves the full "org/model" name
* - If the model name has no slash or multiple slashes, extracts just the filename
* - If the model name is just a filename (no path), returns it as-is.
*
* @param modelName - The model name or path to normalize
* @returns The normalized model name
*
* @example
* normalizeModelName('models/llama-3.1-8b') // Returns: 'llama-3.1-8b' (multiple slashes -> filename)
* normalizeModelName('C:\\Models\\gpt-4') // Returns: 'gpt-4' (multiple slashes -> filename)
* normalizeModelName('meta-llama/Llama-3.1-8B') // Returns: 'meta-llama/Llama-3.1-8B' (Hugging Face format)
* normalizeModelName('simple-model') // Returns: 'simple-model' (no slash)
* normalizeModelName(' spaced ') // Returns: 'spaced'
* normalizeModelName('') // Returns: ''
