Add implicit conversion to Result<TValue, TError> #9

Proposal

Add implicit conversion operators allowing a plain TValue to be converted into Result<TValue, TError>.Likewise allow TError to be implicitly converted into Result<TValue, TError> as an Err variant.

Motivation

• Improve ergonomics: callers can return values/errors directly without wrapping them in Result constructors.
• Reduce boilerplate in functions that frequently return Result.

Examples

Before:
return new Result(value);
return new Result(error);

After:
return value; // converts to new(value)
return error; // converts to new(error)
