### Purpose Linked issue: N/A Support deletion vector cardinality in index manifest metadata so scan planning can preserve the value when building deletion files. ### Brief change log - introduce `DeletionVectorMeta` to replace the raw `(offset, length)` tuple used by deletion vector ranges - deserialize and serialize optional `_CARDINALITY` from index manifest metadata - propagate deletion vector cardinality into `DeletionFile` during table scan planning - add a unit test for cardinality propagation and refresh the index manifest fixture test to use the production reader and current fixture data ### Tests - `cargo test -p paimon spec::index_manifest::tests -- --nocapture` ### API and Format - no public API changes - extends index manifest metadata handling to preserve optional deletion vector cardinality when present in storage ### Documentation - N/A -- This is an automated message from the Apache Git Service.
