Migration to TypeScript with type-safe reasons array

[ronakmaheshwari]

This PR introduces a full TypeScript upgrade, improving maintainability and scalability by structuring the codebase and data more robustly.

🔧 What’s Changed

• Codebase migrated from JavaScript to TypeScript (*.ts files)
• Replaced dynamic fs.readFileSync usage
• reasons.json is now a proper TypeScript module (reasons.ts)
• No file system access required at runtime
• Introduced convert.ts utility
• Converts a string[] JSON file into a typed { reason: string }[] format
• Added type safety
• Defined Reason interface
• Enforced Reason[] typing for the reasons array

🎯 Why It Matters
✅ TypeScript provides a better developer experience with static type checks

✅ Eliminates runtime file I/O in favor of static imports

✅ Structured reasons array prepares the codebase for future features (e.g., filtering, categorization, tagging)

🧪 How to Test
Run the app as usual (npm run dev)

Test endpoint (e.g., /random-reason) still returns a valid JSON object:
{ reason: "..." }

Types validated via tsc with no type errors

Use a "No" HTTP response code somewhere in the 4xx range #6
