v0.5.0

Added

• Type conversion traits for integers and decimals:
  • Cast — type-safe, infallible conversion (e.g., widening or lossless transforms).
  • TryCast — checked conversion returning an error on overflow, sign mismatch, or incompatible scale.
  • Supported families: unsigned/signed big integers (U64, U128, U256, U512, U1024, and I64, I128,
    I256, I512, I1024) #42 and decimals (UD64, UD128, UD256, UD512, UD1024, and D64, D128, D256,
    D512, D1024).
  • Common scenarios:
    • Widening cast for integers — via Cast.
    • Checked narrowing cast — via TryCast, with overflow errors.
    • Conversions between unsigned and signed integers — TryCast rejects negative/out-of-range values.
    • Conversions between UD* and D* — proper sign/scale propagation with checks in TryCast.
• Const-generic “dimensions” for conversion direction checks:
  • Internal Widen/Narrow markers ensure Cast/TryCast correctness without unstable generic const expressions.

Deprecated

• Decimal .transmute() is now deprecated (since "0.5.0"); removal is planned for a future major release.
  Use .resize() or cast via Cast and TryCast traits instead.

Documentation

• Minor fixes and clarifications; added usage examples for type conversions.
