Feature / add watch script

Description

This PR adds a watch script to the package.json to automate the rebuild process upon file changes, which will improve development workflow. The webpack.config.js file was also updated to configure the watchOptions, optimizing performance and ensuring that file changes trigger automatic rebuilds without including unnecessary files. This change eliminates the need for manual rebuilds during development. Also Documentation is updated to include usage instructions for the new watch command

[x] A new yarn watch command is available
[x] The command successfully watches for file changes in the root directory
[x] Changes to source files trigger an automatic rebuild
[x] The console provides clear output about the rebuild process
[x] Documentation is updated to include usage instructions for the new command

Relevant Motivation & Context

Developers previously needed to manually rebuild the project after every change, which slowed down the development process. Adding a watch script and configuring watchOptions will improve efficiency by automatically rebuilding on changes.
