Clean up stale patch files from repository root

[DeFiVC]

What

Remove the temporary patch files (patch7.js through patch13.js) from the repository root. These are one-off scripts that should not be committed to the repo.

Why

Stale patch files:

• Clutter the project root
• Confuse contributors about their purpose
• Are likely no longer needed since the codebase has evolved past them
• Violate the principle of keeping the repo clean

Scope

• Delete: patch7.js, patch8.js, patch9.js, patch10.js, patch11.js, patch12.js, patch13.js
• Add *.js (except config files) or patch*.js to .gitignore to prevent future occurrences
• No source code changes

Acceptance Criteria

• All 7 patch files are deleted from the root directory
• .gitignore updated to prevent similar files from being committed
• No other files are affected
