convert_local.py

Reads a local Excel file and converts its contents into a structured prompt library
under `prompt-library/` per the development guide. It generates:
- prompts/<category>/ (one file per non-empty cell across columns for each prompt row)
- prompts/index.json (summary + traceability)
- prompts/<category>/index.md (table + version matrix)
- docs/tools.md, docs/support.md, docs/excel-data.md
- README.md (top-level for prompt-library)

Usage:
  python prompt-library/scripts/convert_local.py \
    [--excel "/absolute/or/relative/path/to/prompt (2).xlsx"] \
    [--config prompt-library/scripts/config.yaml] \
    [--category-name prompt-category]

If no arguments are provided, it will:
- load config from prompt-library/scripts/config.yaml (if present)
- resolve Excel path from config.source.excel_file relative to project root
- default category to "prompt-category"

Dependencies: pandas, openpyxl, PyYAML
