refactor: overhaul request engine with Undici and modularize main process

Summary:
- Upgraded HTTP request engine from standard fetch to Undici for high-performance networking.
- Optimized Undici with a global Agent, connection pooling, and automatic redirection handling via interceptors.
- Decoupled core logic from src/main/index.ts into dedicated handlers (requestHandler.ts, pdfHandler.ts).
- Cleaned up main process by removing template bloat and isolating external dependencies.
- Fixed PDF export layout bug where long URLs and JSON values were being cut off (added word-wrapping for code blocks).
Key Files:
- src/main/requestHandler.ts (New)
- src/main/pdfHandler.ts (New)
- src/main/index.ts (Refactored)

-## 🌟 Overview
-
-**API Documenter** is a robust alternative to Postman and Insomnia, designed specifically for developers who value privacy, speed, and ownership. It starts as a high-performance local desktop app but scales instantly into a team-oriented platform with secure database synchronization and granular role-based access control.
-
-## 🚀 Key Features
-
-### 1. Offline-First Excellence
-- **Local Storage**: Your sensitive API data stays on your machine by default using high-speed IndexedDB (Dexie).
-- **Zero Latency**: No "cloud sync" lag while you're prototyping or testing locally.
-- **Privacy by Design**: No mandatory accounts or telemetry.
-
-### 2. Secure Team Synchronization
-- **Multi-DB Support**: Connect your workspace to a remote **PostgreSQL** or **MySQL** server.
-- **Vercel Proxy Deployment**: Deploy a production-ready server to Vercel in one click. This ensures your DB credentials are never exposed to the client side and all team traffic is securely authorized.
-- **Real-time Sync**: Collaborative editing with bi-directional synchronization between local and remote states.
-
-### 3. Folder-Level RBAC
-- **Admin**: Full control over project infrastructure, sync settings, and team management.
-- **Editor**: Full read/write access to folders, requests, and documentation.
-- **Viewer**: Read-only access for team members who need to consume documentation without modification.
-
-### 4. Advanced Request Engine
-- **Full HTTP Support**: GET, POST, PUT, DELETE, PATCH, OPTIONS, and more.
-- **Rich Payloads**: Seamlessly handle Headers, Query Params, and JSON/Text bodies.
-- **Smart Response Viewer**: Real-time status codes, response headers, body size, and execution benchmarks.
-
-### 5. Enterprise-Grade Scaling
-- **Premium UI**: Sleek, glassmorphic dark-themed design.
-- **Custom Font Scaling**: Perfectly tailored readability for any screen size, from laptop screens to 4K monitors.
-- **GitHub Auto-Updates**: Silent background updates that keep you on the latest version without disruption.
-
-## 🛠️ Tech Stack
-
-- **Frontend**: React 18, TypeScript, Vite
-- **Desktop Layer**: Electron (Standard IPC Integration)
-- **State Management**: Zustand & React Query
-- **Local Database**: Dexie (IndexedDB)
-- **Remote Bridge**: mysql2, pg (via Secure Proxy)
-- **CI/CD**: GitHub Actions & Electron-Builder
-
-## � Getting Started
-
-### Prerequisites
-- [Node.js](https://nodejs.org/) (v18.x or v20.x recommended)
-- [npm](https://www.npmjs.com/)
-
-### Installation & Setup
-
-1. **Clone the repository:**
-   ```bash
-   git clone https://github.com/PraneethKulukuri26/API-Documenter.git
-   cd API-Documenter
-   ```
-
-2. **Install dependencies:**
-   ```bash
-   npm install
-   ```
-
-3. **Start Development Server:**
-   ```bash
-   npm run dev
-   ```
-
-4. **Build Production Application:**
-   ```bash
-   # Build for Windows
-   npm run build:win
-
-   # Build for macOS
-   npm run build:mac
-   ```
-
-## 🛡️ Security
-
-API Documenter uses a unique **Security Proxy Architecture**. When you connect a database, the app deploys a serverless function to Vercel. This function acts as the sole gatekeeper for your database, ensuring that raw SQL credentials are never stored in the desktop application but remain securely in your Vercel environment variables.

+  # API Documenter
+  ### The Professional Self-Hosted API Ecosystem
+
+  **Postman Power + Enterprise Control + 100% Data Ownership.**

+
+## 🌟 The Vision
+
+**API Documenter** is more than just an API client; it is a complete **Documentation and Testing Ecosystem**. It was built for engineering teams that cannot compromise on data privacy or reliability. While existing tools force your sensitive API keys and internal endpoints onto their cloud, API Documenter keeps your data exactly where it belongs: **on your machine and in your private database.**
+
+---
+
+## 🚀 Master Feature Suite
+
+### 1. 📂 Folder-Level RBAC (Enterprise Security)
+The first self-hosted tool to offer granular, folder-level **Role Based Access Control**.
+- **Admins**: Manage project connections, deployment settings, and global team permissions.
+- **Editors**: Create and modify endpoints within specific folders they have access to.
+- **Viewers**: Access real-time documentation and test endpoints without risk of modifying team data.
+- **Team Isolation**: Different members can have different roles on different folders within the same project.
+
+### 2. 📝 Advanced Documentation Engine
+A dedicated workspace for crafting beautiful, production-ready API documentation.
+- **Markdown-Native**: Write documentation using standard Markdown with real-time side-by-side preview.
+- **Smart Components**: Insert **Smart Table of Contents**, **Page Breaks**, and dynamic code blocks.
+- **Built-in PDF Compilation**: Export high-fidelity A4 documentation PDFs using a built-in Chromium engine (no external Chrome dependency required).
+- **Distraction-Free Mode**: Collapse all sidebars and toolbars to focus purely on the content.
+
+### 3. 🔄 Advanced Database Synchronization
+Bypass the proprietary cloud and sync directly with your own infrastructure.
+- **Native Support**: Direct integration with **MySQL** and **PostgreSQL**.
+- **Vercel Proxy Bridge**: One-click deployment of a secure RBAC proxy. Your database credentials stay encrypted in Vercel environment variables—never stored on user machines.
+- **Real-Time Connectivity**: Instantly syncs changes across team members while maintaining an offline-first cache for zero-latency editing.
+- **Smart Error Recovery**: Robust handling for VPN/Firewall interruptions with detailed connection error reporting and one-click retry.
+
+### 4. ⚡ High-Performance Request Engine
+A testing suite built for speed and precision.
+- **Complete Method Support**: GET, POST, PUT, DELETE, PATCH, and OPTIONS.
+- **Variable Injection**: Multi-environment support with dynamic variable substitution in URLs, Headers, and Bodies.
+- **Response Analytics**: Real-time benchmarks for execution time, payload size, and status codes.
+- **Rich Body Support**: JSON (with syntax highlighting), Key-Value pairs, and raw text.
+
+### 5. 🎨 Aesthetic & Ergonomic UI
+Designed for developers who spend 8+ hours a day in their tools.
+- **Premium Monochrome Design**: A sleek, glassmorphic dark-mode interface that reduces eye strain.
+- **Dynamic Font Scaling**: Global font scaling (10px to 20px) ensures accessibility and comfort on any display density.
+- **Zero-Flicker Performance**: Optimized React components and IndexedDB caching for a snappy, native feel.
+
+---
+
+## 🛠️ Technical Architecture
+
+API Documenter is engineered with a **Security-First** mindset:
+
+- **Frontend**: React 18 & TypeScript for type-safe UI logic.
+- **Desktop Layer**: Electron with a hardened IPC bridge.
+- **Local Persistence**: **Dexie.js (IndexedDB)** for ultra-fast, offline-first data storage.
+- **Remote Bridge**: A serverless **Node.js Proxy** (deployed to Vercel) that handles DB pooling and RBAC authorization without exposing internal ports.
+- **State Engine**: **Zustand** for lightweight UI state and **React Query** for robust server-state synchronization.
