Add generic TODO comments to all files for code review improvements

[Copilot]

This PR adds a generic TODO comment to every file in the repository to mark them for future review and improvements. The comments are added using appropriate syntax for each file type:

Changes Made

• JavaScript files (hardhat.config.js, scripts/*.js, test/*.js): Added // TODO: review this file for improvements
• Solidity contracts (contracts/*.sol): Added // TODO: review this file for improvements after the SPDX license identifier
• YAML files (.github/workflows/ci-cd.yml, Actions): Added # TODO: review this file for improvements
• Markdown files (README.md): Added <!-- TODO: review this file for improvements -->

Files Modified

• README.md
• hardhat.config.js
• contracts/SEQICO.sol
• contracts/SEQToken.sol
• scripts/deploy.js
• scripts/deploy-DE.js
• test/SEQICO.test.js
• .github/workflows/ci-cd.yml
• Actions

Implementation Details

The TODO comments are placed at the appropriate location for each file type:

• For Solidity files, the comment is added after the SPDX license identifier to maintain standard contract structure
• For JavaScript files, the comment is added at the very beginning before imports
• For YAML files, the comment is added at the top using hash syntax
• For Markdown files, HTML comment syntax is used to avoid affecting the rendered output

All changes are minimal and surgical - exactly one line added per file with no deletions or modifications to existing code. The syntax validity of all files has been verified and no functionality is affected.

Files like LICENSE, package.json, and package-lock.json were intentionally skipped as they either don't support comments or are auto-generated files that shouldn't be manually modified.

This pull request was created as a result of the following prompt from Copilot chat.

Add a generic TODO comment (e.g., // TODO: review this file for improvements) at the top of every file in the repository, regardless of file type (JavaScript, Solidity, YAML, Markdown, etc.). Ensure each file begins with an appropriate TODO comment in the syntax matching the file type. For example, use '//' for JS/Solidity, '#' for YAML, and '' for Markdown. After this is complete, proceed to further tasks as requested by the user.
