[Fix] Validate Pipe payload lengths before allocation

[Caideyipi]

Description

Validate length-prefixed Pipe strings and binary payloads against the remaining request body before decoding V1/V2 handshakes, slices, and receiver-runtime cleanup requests. Also reject V2 handshake parameter counts that cannot fit in the body. Malformed payloads now return the existing PIPE_ERROR response, including through compressed wrappers.

Valid wire encoding, null/empty strings, and handshake buffer positions remain compatible.

Validation

• All 77 tests passed across PipeTransferRequestValidationTest, PipeTransferSliceReqBuilderTest, PipeTransferCompressedReqTest, PipeDataNodeThriftRequestTest, and PipeReceiverTest.
• Full English reactor build and targeted tests:

  mvn -o test -Dtest=PipeTransferRequestValidationTest,PipeTransferSliceReqBuilderTest,PipeTransferCompressedReqTest,PipeDataNodeThriftRequestTest,PipeReceiverTest -Dsurefire.failIfNoSpecifiedTests=false -Dmaven.build.cache.enabled=false
  

• Full Chinese reactor compilation:

  mvn -o test-compile -P with-zh-locale -DskipTests -Dmaven.build.cache.enabled=false
  

• Spotless and Checkstyle passed. Both reactor builds used MAVEN_OPTS=-Xmx2g.

This PR has:

• been self-reviewed.
• added comments explaining the allocation checks.
• added parser and receiver regression tests.

Key changed/added classes

PipeTransferPayloadReader, PipeTransferHandshakeV1Req, PipeTransferHandshakeV2Req, PipeTransferSliceReq, and PipeTransferPipeReceiverRuntimeInfoCleanupReq.
