package .bin/ scripts as proper nix packages, delete .bin/

Packaged 14 scripts from .bin/ into packages/ with proper dependency declarations (writers.writeDashBin/writeBashBin/writePython3Bin): - 256color → two56color (terminal color chart) - avesta.sed → avesta (Avestan transliteration) - bvg.sh → bvg (Berlin transit disruptions) - unicode → charinfo (Unicode character info) - chunk-pdf → chunk-pdf (split PDFs by page count) - csv2json → csv2json (CSV to JSON converter) - fix-sd.sh → fix-sd (exFAT SD card recovery, improved output handling) - json2csv → json2csv (JSON to CSV converter) - mp3player-write → mp3player-write (audio conversion for MP3 players) - mushakkil.sh → mushakkil (Arabic diacritization) - nix-haddock-index → nix-haddock-index (GHC Haddock index generator) - pdf-ocr.sh → pdf-ocr (OCR PDFs via tesseract) - prospekte.sh → prospekte (German supermarket flyer browser) - readme → readme (GitHub README as man page) All added to overlay and packages output. .bin/ directory removed.
