This PR fixes a potential memory leak in the compression path. In the current implementation, if zstd_compress returns an error, rb_raise is called immediately. If rb_raise will be called, the subsequent ZSTD_freeCCtx(ctx) is never reached. This change ensures that ZSTD_freeCCtx(ctx) is called before raising the exception, preventing the context leak. Seems zstd_compress errors are rare in practice, this fix ensures safety for those edge cases.
