refactor: fix Kreisel spelling throughout codebase

[Copilot]

Every occurrence of the misspelling "Kriesel" (as in Georg Kreisel) has been corrected to "Kreisel". This includes a secondary variant "Krisel" (missing 'e') found in SatisfiesKriselPutnamCondition.

  • Entailment/KrieselPutnam.lean → KreiselPutnam.lean
  • Kripke/AxiomKrieselPutnam.lean → AxiomKreiselPutnam.lean
  • Kripke/Logic/KrieselPutnam.lean → KreiselPutnam.lean

• Identifier/name renames across 7 files:

  • HasKrieselPutnam → HasKreiselPutnam
  • SatisfiesKriselPutnamCondition → SatisfiesKreiselPutnamCondition
  • kriesel_putnam / krieselputnam → kreisel_putnam / kreiselputnam

  • All import paths updated accordingly
