Error Taxonomy Map (v1.54.0)

Both REslava.Result.Flow and REslava.ResultFlow now emit a _ErrorTaxonomy constant alongside the pipeline diagram constants. It is a markdown table of every detectable error type per method, generated at compile time — no runtime cost, no extra tooling.

Activation — automatic for any class that has at least one [ResultFlow] method. No attribute needed.

Two confidence levels:

Source	Confidence	How detected
Result<T, TError> return type	certain	Generic type argument — exact, from symbol
Fail(new XxxError(...)) in method body	inferred	Object creation in body scan
Ensure(..., new XxxError(...)) in method body	inferred	Object creation in body scan

public partial class OrderService
{
    [ResultFlow]
    public Result<Order, NotFoundError> GetOrder(int id) => ...;

    [ResultFlow]
    public Result<Order> PlaceOrder(OrderRequest req) =>
        Result<Order>.Ok(new Order())
            .Bind(ValidateRequest)          // throws ValidationError
            .Ensure(HasStock, new OutOfStockError("no stock"))
            .Map(FulfillOrder);
}

Generated constant in Generated.ErrorTaxonomy.OrderService_ErrorTaxonomy:

public const string _ErrorTaxonomy = @"
| Method | Error Type | Confidence |
|---|---|---|
| GetOrder | NotFoundError | certain |
| PlaceOrder | OutOfStockError | inferred |
| PlaceOrder | ValidationError | inferred |
";

REslava.ResultFlow (syntax-only) uses a name heuristic instead of IError interface resolution — types ending in Error or Exception are matched. Confidence labels are identical.
