Add numeric precision options

[aki-null]

Added

• Configurable Numeric Precision: New Compiler(IntegerPrecision, FloatPrecision) constructor
  • Integer: Integer (32-bit, default) or Long (64-bit)
  • Float: Float (32-bit, default), Double (64-bit), or Decimal (128-bit)
• CompiledScript API Expansion: New properties for accessing values at different precisions
  • Added LongValue, DoubleValue, DecimalValue properties
  • Added IntegerPrecision and FloatPrecision properties to query compiler configuration
• VariableValue API Expansion: Support for all numeric precision types
  • New constructors: VariableValue(long), VariableValue(double), VariableValue(decimal)
  • New properties: LongValue, DoubleValue, DecimalValue with automatic type conversion
• Precision-Aware Operations: Variables and expressions automatically adapt to compiler precision
  • Variables auto-convert to match compiler precision during evaluation
  • Assignment operators correctly handle cross-precision conversions
  • Original variable types preserved; conversion happens only during expression evaluation

Changed

• Performance Improvements: Float precision operations optimized
  • Built-in float functions now use MathF instead of casting System.Math
  • Aggressive inlining on hot-path value property accessors
  • Switch expressions used for type dispatch, reducing branching overhead
