fix: Handle Value types correctly in RPN operations

- Updated HyperMultiply, HyperSubtract, HyperDivide, HyperPower, HyperModulo
  to use []Value and toNumber() for Value-to-float64 conversions
- Updated HyperLog2, HyperLog10, HyperLn to use []Value and toNumber()

- Fixed rpn.go:
  - Stack.Push() now uses NewNumberValue() for float64 values
  - GetCurrentStack() converts []Value to []float64
  - show() output uses toNumber() for Value formatting
  - Variable handling uses NewNumberValue() when pushing

- Fixed test files (operations_test.go):
  - Updated all Stack.Push() calls to use NewNumberValue()
  - Updated Pop() comparisons to use .Number() method
  - Fixed format specifiers for Errorf() calls

All tests pass and the binary builds and runs correctly.
