[Feature] Add Pipe logical backup sink and import tooling

[Caideyipi]

Summary

• add built-in logical-backup-sink / logical-backup-connector plugins that persist Pipe metadata and data events as ordered WAL-like .pwal segments
• add CRC32C/SHA-256 integrity checks, atomic manifests, segment recovery/rotation, directory locking, append identity validation, and committed event groups
• require DataRegion logical backup tasks to explicitly configure sink.resume=append (or connector.resume=append), with validation directing operators to use a shared backup directory so leader changes resume the same archive; SchemaRegion keeps its existing default
• support tablet, TsFile, delete, schema plan/snapshot, heartbeat, and terminate records for tree and table models
• provide inspect, verify, export, and import commands with safe ZIP handling, dry-run, schema-first replay, and replay request allowlisting
• checkpoint imports after every request and accept the receiver idempotent-conflict status, so recovery can safely replay at most the request whose checkpoint write was interrupted
• package Linux and Windows import/export wrappers in the CLI distribution and provide English/Chinese messages

Validation

• node-commons logical-backup tests: 32 passed (LogicalBackupWriterTest, LogicalBackupArchiveReaderTest)
• CLI tests: 7 passed (PipeLogicalBackupToolTest)
• DataNode validation tests: 2 passed (LogicalBackupSinkTest)
• English compilation/tests and Chinese-locale test-compile passed for the changed DataNode and CLI modules
• Spotless, Checkstyle, and forbidden-apis checks passed for the changed modules
