Pull Request Overview

This PR introduces a new parameter building mechanism for YDB queries, replacing the ParamsFromMap approach with a structured ParamsBuilder pattern. The changes modernize query execution by using type-safe parameter builders and simplifying result set iteration.

• Replaces ydb.ParamsFromMap with ydb.ParamsBuilder() for parameter construction
• Updates YDB query methods to use QueryResultSet and direct row iteration
• Normalizes decimal type name casing from "Decimal" to "decimal"

There's trailing whitespace on line 162 that should be removed.

The panic message should include the actual column type that wasn't recognized. Consider including sdk.DataType(field.Column.Type) in the error message to help with debugging.

Suggested change

	panic(fmt.Sprintf("unknown YDB column type for param %s (goType=%s)", name, goType))
	panic(fmt.Sprintf("unknown YDB column type for param %s (goType=%s, columnType=%s)", name, goType, sdk.DataType(field.Column.Type)))

The TODO comment should specify which types need to be supported or reference an issue. An empty return value could lead to the panic in YDBParamsBuilder without clear indication of what's missing.

Suggested change

	//TODO: support other types
	// TODO: support additional YDB types such as Decimal, UUID, DyNumber, Optional, List, Tuple, Struct, Dict, Variant, Void, Null, and others as needed.
	// See https://github.com/ydb-platform/ydb-go-sdk/blob/main/table/types/types.go for the full list of YDB types.
