feat: Add native binary analyzer test utilities and implement SM2 signing tests

- Introduced `NativeTestBase` class for ELF, PE, and Mach-O binary parsing helpers and assertions.
- Created `TestCryptoFactory` for SM2 cryptographic provider setup and key generation.
- Implemented `Sm2SigningTests` to validate signing functionality with environment gate checks.
- Developed console export service and store with comprehensive unit tests for export status management.
