<!-- PR titles must follow Conventional Commits: <type>(<optional-scope>): <description> --> ### Purpose <!-- Linking this pull request to the issue --> Linked issue: #316 <!-- What is the purpose of the change --> This change extracts BTree-specific sorted index utilities into reusable global index components, preparing them for the bitmap global index implementation. The main changes are: - Move `KeySerializer` from the BTree directory to the common global index directory. - Change `KeySerializer` from a static utility into a reusable instance associated with a key type and memory pool. - Rename `BTreeIndexMeta` to `SortedIndexFileMeta`, matching the corresponding Java class. - Rename `BTreeFileMetaSelector` to `SortedFileMetaSelector`, matching the corresponding Java class. - Update BTree writers and readers to reuse the common serializer, metadata, and file selector. - Preserve existing BTree serialization bytes, metadata compatibility, and query behavior. - Keep validation for malformed serialized keys and invalid min/max metadata. This is a preparatory refactoring. Bitmap global index format support and range/string fallback will be implemented separately. ### Tests <!-- List UT and IT cases to verify this change --> ### API and Format <!-- Does this change affect API in include dir or storage format or protocol --> ### Documentation <!-- Does this change introduce a new feature --> ### Generative AI tooling Generated-by: OpenAI Codex (GPT-5) <!-- If generative AI tooling has been used in the process of authoring this patch, please include the phrase: 'Generated-by: ' followed by the name of the tool and its version.
