fix: correct absolute path creation in create-tool script

[Devendra8839]

Description

This PR fixes an issue in the create-tool scaffold script where tool generation failed on Unix-based systems due to incorrect absolute path handling.

Problem

Running the scaffold generator command resulted in partially created directories followed by an ENOENT error during file creation.

Example failure:

Error: ENOENT: no such file or directory

The issue occurred because recursive directory creation was initialized using a relative root (.) even when processing absolute paths.

As a result, directories were incorrectly generated as relative paths such as:

home/user/project/...

instead of the expected absolute paths:

/home/user/project/...

This caused subsequent scaffold files (such as index.tsx) to fail during creation because the target absolute directory structure did not actually exist.

Root Cause

Inside createFolderStructure(), recursive folder creation was initialized with:

recursiveCreate('.', 0);

Using . as the starting base path caused absolute path segments to be resolved relative to the current working directory during recursive joins.

Fix

The recursive creation process now starts from the filesystem root using:

recursiveCreate(sep, 0);

This ensures absolute paths are preserved correctly during recursive directory creation and allows the scaffold generator to successfully create all required files and directories on Unix-based systems.
