### Purpose Add the standalone `ManifestSidecar` implementation and the complete version-1 format for independent partition, row-ID and bucket coverage over physical Avro manifest blocks. It includes bounded construction, validation, block selection, sequential reads of selected blocks, and optional caching of sidecar bytes and compressed blocks. Keep this PR limited to the new class, its tests and fixtures, and the format documentation. Settings are supplied explicitly, bucket matching uses a predicate, and block cache keys live inside the class. Existing table writers, scans, configuration definitions and cleanup paths are unchanged; automatic integration belongs in follow-up PRs. ### Tests - Golden format fixtures for all three payloads, conservative budget degradation, malformed input and independent filter short-circuiting. - Sidecar and block caches, overlapping selections, partial reads, truncation and I/O failures. - Build sidecars from real manifests and raw-block rewrites, then decode selected blocks using the existing Avro reader. Local Java 8 validation: 46 tests passed, with Checkstyle and Spotless checks enabled: ```text mvn -B -ntp -nsu -pl paimon-core -am -DwildcardSuites=none -DfailIfNoTests=false -Dflink.forkCount=2 -Dtest=ManifestSidecarTest,ManifestBlockIndexTest test ``` -- This is an automated message from the Apache Git Service.
