file-reading — router by file type

When asked to read or summarize a file, dispatch by extension to the appropriate skill under org/public/core/:

Extension	Skill	Script
.pptx	pptx	python org/public/core/pptx/extract.py
.docx	docx	python org/public/core/docx/extract.py
.xlsx	xlsx	python org/public/core/xlsx/extract.py
.pdf	pdf	python org/public/core/pdf/extract.py
.txt, .md	—	cat
.csv	—	cat (or column -t -s, for alignment)
.json	—	cat (or jq . if structure matters)

For extensions not listed, read the corresponding SKILL.md under org/public/core/ if one exists, otherwise fall back to file <path> to identify the format and proceed manually.
