/**
 * Port interface for bitmap index storage operations.
 *
 * This port defines the contract for persisting and retrieving
 * the sharded bitmap index data. Adapters implement this interface
 * to store indexes in different backends (Git, filesystem, etc.).
 *
 * This port is a subset of the focused ports: it uses methods from
 * BlobPort (writeBlob, readBlob), TreePort (writeTree, readTreeOids),
 * and RefPort (updateRef, readRef).
