[FEATURE]: Add automated template initialization script to replace placeholders and streamline project setup

### Feature and its Use Cases

## Feature Overview

Currently, users must manually replace multiple TODO placeholders (e.g., project name, description, tech stack) when using this template repository.

This process is repetitive, error-prone, and slows down onboarding, especially for beginners.

## Proposed Feature

Introduce an automated initialization script (e.g., setup.js or CLI tool) that:

- Prompts users for project details (project name, description, tech stack, etc.)
- Automatically replaces placeholders across key files:
- README.md
- CONTRIBUTING.md
- Other template files if applicable
- Ensures no unresolved TODO placeholders remain

## Use Cases

- A new contributor creates a project using this template and runs:

node setup.js

→ The script configures the project automatically

- Reduces manual editing effort and prevents missing placeholders
- Helps standardize project setup across AOSSIE repositories

## Expected Outcome

- Faster onboarding for developers
- Cleaner and fully initialized repositories
- Improved usability and scalability of the template

### Additional Context

## Additional Context

- This can be initially implemented as a simple Node.js script and later extended into a CLI tool (e.g., npx create-aossie-project)
- The script can use basic file reading and string replacement to update placeholders
- Future enhancements could include:
- Multi-stack support (Node.js, Python, etc.)
- Validation to ensure no TODO placeholders remain
- Integration with CI checks

This enhancement aligns with improving developer experience and automation within the template repository.
