generated a library that wraps the go expr parser, and embedded that into libmilvus-core.so issue: https://github.com/milvus-io/milvus/issues/45702 see `internal/core/src/plan/milvus_plan_parser.h` for the exposed interface <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Introduced C++ API for plan parsing with schema registration and expression parsing capabilities. * Plan parser now available as shared libraries instead of a standalone binary tool. * **Refactor** * Reorganized build system to produce shared library artifacts instead of executable binaries. * Build outputs relocated to standardized library and include directories. <sub>✏️ Tip: You can customize this high-level summary in your review settings.</sub> <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Signed-off-by: Buqian Zheng <zhengbuqian@gmail.com>
