Adaptiver GA-Zyklus, Pool-Groessen-Panel, Konfig direkt aus cfg-Dateien

Zyklus/Farm:
- neuer adaptiver Modus: grosse Startpopulation, die je Generation
  schrumpft (Start/Schrumpfung/MinPopulation) und bei Konvergenz stoppt
  (Geduld Generationen ohne Verbesserung >= Schwelle, max MaxGenerationen)
- Zyklus.laden erkennt adaptives Profil am Feld 'Start' (Modus adaptiv),
  sonst klassisch (Abfolge/Anzahl); Farm._LaufStatisch/_LaufAdaptiv
- neue Trunkierungs-Selektion Farm.PopulationBegrenzen
- [Adaptiv]-Profil in zyklus.cfg (dokumentiert)

Entwicklungsgrafik:
- zweites Panel unter dem Verlauf zeigt die Anzahl erzeugter
  Verteilungen im Pool je Schritt (gemeinsame Zeitachse)

Konfiguration:
- platz.cfg entfernt; zyklus.cfg/strafen.cfg werden direkt aus
  $PLATZ_CFG geladen
- neuer Schalter --zyklus-art (Default Adaptiv) waehlt das GA-Profil
- web/main.py analog: direktes Laden, Profil via PLATZ_ZYKLUSART

Doku (README.md, CLAUDE.md) und Tests entsprechend aktualisiert;
Beispiele mit dem Adaptiv-Default neu berechnet.
