PCC-Decoder-Bugfix: RLE-Runs duerfen Zeilengrenzen ueberschreiten (Row-Reset war falsch)

Browse Source

Stefan hat zurecht bemaengelt dass KARTE.PCC/KELLOGGS.PCC verzerrt/verrutscht
aussehen (Smacks-Frosch an falscher Position, Notch-Fehlstelle im Logo-Rahmen).

Root Cause: Der Decoder hat RLE-Runs am Ende jeder Bildzeile hart abgeschnitten
und den Rest verworfen (klassisches PCX-Verhalten angenommen). Dieses Format
haelt sich aber NICHT an die PCX-Konvention 'ein Run ueberschreitet nie eine
Zeile' -- Runs laufen frei ueber Zeilengrenzen. Verifiziert per Pixel-fuer-Pixel-
Vergleich gegen echten DOSBox-Screenshot (world map): mit durchgehender
Dekodierung (kein Row-Reset) ist das Ergebnis jetzt pixel-identisch zur Referenz.

- tools/pcc_to_png.py: Row-Reset entfernt, decodiert jetzt width*height Pixel
  am Stueck aus dem RLE-Strom
- png_out/: alle 77 PNGs mit dem Fix neu generiert
- tools/wip_bob_sprite_research/: Backup der laufenden (noch ungeloesten)
  BOB-Sprite-Format-Exploration von aria-wohnung, damit nichts bei einem
  VM-Neustart verloren geht
- NOTES.md: Root-Cause-Analyse dokumentiert, alte Fehldiagnose ('byte-identisch
  zwischen Row-Reset und kontinuierlich') korrigiert, Rauser-Intro-Frage
  beantwortet (3 Frames vorhanden, Text-Logo, keine Video-Datei)
