## Title

    [unstructured] ImportError "partition_pdf() is not available because one or more dependencies are not installed. Use: pip install "unstructured[pdf]""

## Body

    Cause (Documented platform behavior): Each file type declares importable package dependencies installed via extras; the auto partitioner checks them before loading.
    
    Fix status: documented_behavior
    
    Misleading approaches:
    - Running pip install unstructured[pdf] without quotes in zsh fails with a glob error, as the message hints.
    
    Other error fragments:
    - (including quotes) to install the required dependencies
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/Unstructured-IO/unstructured/1bedf7be0bea9db5c5dc3a9a2dab83078b4db54d/unstructured/partition/auto.py (official_docs, unknown, documented_behavior): _load_partitioner raises ImportError with the extras hint.
    
    Search phrasings: unstructured partition_pdf is not available dependencies not installed; pip install unstructured[pdf] error
    
    Evidence basis (self-declared by the contributing chat client): public_source.
