test(cdc): reproduce connector registration gap on live develop

[seonghobae]

Rebuilds issue #200 from the exact current protected develop tip while preserving the original fail-first branch and Draft #313 as historical evidence.

Exact live base incorporated: feaea5d2a353d74919afc9a6971e8c15da5dd2f3. Exact replacement head: 7b900d0920ddd477f988d46c600a264ea40721ae. The head preserves the original RED commit 6b377351675352797d35da9404c502722f26e385 as ancestry and merges the live protected base without force-push or rewritten evidence. Relative to current develop, the only content delta is cdc-service/src/test/java/com/xtrmetl/cdc/spi/CdcRegistryIdentityTest.java.

Keep Draft until fresh exact-head CI proves the intended production-boundary failures on real CdcSourceRegistry/CdcTargetRegistry behavior. Only then apply the narrow fail-closed registration validation, duplicate rejection, immutable registry view, and public-contract Javadoc. No review/check evidence from #313 or another head transfers.

Summary by CodeRabbit

• 개선 사항

  • CDC 소스 및 대상 커넥터 등록 시 null 값, 빈 식별자, 중복 식별자를 거부합니다.
  • 동일한 식별자의 기존 커넥터가 덮어써지지 않습니다.
  • 커넥터 목록이 등록 순서대로 제공되며, 조회 결과를 임의로 변경할 수 없습니다.
  • 기본 Kafka 및 JDBC 커넥터 기능은 기존과 동일하게 유지됩니다.

• 검증

  • 잘못된 등록 요청, 목록 변경 시도 및 Spring 연동 동작에 대한 검증을 강화했습니다.

CDC 레지스트리 무결성

Layer / File(s)	Summary
등록 검증 및 불변 스냅샷 cdc-service/src/main/java/com/xtrmetl/cdc/spi/CdcSourceRegistry.java, cdc-service/src/main/java/com/xtrmetl/cdc/spi/CdcTargetRegistry.java	두 레지스트리가 null 커넥터, blank 식별자, 중복 식별자를 IllegalArgumentException으로 거부합니다. 기존 등록을 덮어쓰지 않습니다. all()은 삽입 순서가 유지되는 불변 목록을 반환합니다.
레지스트리 동작 검증 cdc-service/src/test/java/com/xtrmetl/cdc/spi/CdcRegistryIdentityTest.java	중복 등록, 잘못된 입력, 기존 커넥터 보존, all() 결과의 변경 차단을 검증합니다.
