refactor(errors)!: ErrorType → ErrorKind 전면 rename (추상 기반 + 3 레이어)

"ErrorType" 토큰 3중 오버로드(추상 record·프로퍼티·Serilog 필드) 해소의
최종 단계. 분류 의미를 명확히 표현하는 "Kind"로 통일.

변경:
- Src/Functorium/Abstractions/Errors/
  - ErrorType.cs → ErrorKind.cs (추상 record + .Name 프로퍼티)
  - ErrorName 프로퍼티 → Name (더 짧고 명확)
- Src/Functorium/Domains/Errors/DomainErrorType* (11 partial)
  → DomainErrorKind.*.cs
- Src/Functorium/Applications/Errors/ApplicationErrorType* (7 partial)
  → ApplicationErrorKind.*.cs
- Src/Functorium.Adapters/Errors/AdapterErrorType* (10 partial)
  → AdapterErrorKind.*.cs
- 레이어 팩토리 시그니처 갱신:
  - DomainError.For<T>(DomainErrorKind errorKind, ...)
  - ApplicationError.For<T>(ApplicationErrorKind errorKind, ...)
  - AdapterError.For<T>(AdapterErrorKind errorKind, ...)
- 전 레이어 Testing 어설션 시그니처 갱신
- LayerErrorCore, ErrorLogFieldNames XML 주석 정리

상호 구분 유지 (의도적 비-rename):
- ObservabilityNaming.OTelAttributes.ErrorType — OpenTelemetry 의미 규약
  (error.type 표준 키)이므로 그대로 유지
- ObservabilityNaming.ErrorTypes — 내부 에러 분류 카테고리 (Aggregate/
  Exceptional/Expected) 컬렉션 이름이므로 그대로 유지
- ErrorInfoExtractor의 tuple 필드 ErrorType — OTel 태그 값 소스이므로
  OTel 규약과 일치하도록 유지

BREAKING CHANGE:
- 추상 base: public record ErrorType → ErrorKind
- ErrorType.ErrorName (virtual prop) → ErrorKind.Name
- DomainErrorType → DomainErrorKind (커스텀 에러 정의 시
  `: DomainErrorKind.Custom`로 변경 필요)
- ApplicationErrorType → ApplicationErrorKind
- AdapterErrorType → AdapterErrorKind
- 모든 nested sealed record 파생 타입은 자동 rename됨
  (예: DomainErrorType.Empty → DomainErrorKind.Empty)

참고: Docs.Site 가이드·샘플의 ErrorType 참조와 "ErrorCodeFactory"
문서 예시는 Stage 5에서 일괄 갱신.
