feat: add documentation website

[shantoislamdev]

Description

This PR adds a dedicated documentation website under the website/ directory at the project root. The documentation has been thoroughly corrected and updated to match the actual SDK implementation and configuration APIs. Additionally, developer/build dependencies have been refined to ensure seamless local builds on Windows environments.

Key Changes

1. New Documentation Website Module: Added a modern Vite + React + TailwindCSS v4 documentation hub at /website.
2. Corrected SDK Coordinates: Fixed Maven coordinates (com.shantoislamdev -> dev.shantoislam) in Home and Integration Guide pages.
3. Comprehensive Configuration Guide: Expanded the configuration table to fully detail all 15 SDK configuration parameters (such as screenshotQuality, screenshotMaxDimension, pageSettleDebounceMs, etc.).
4. Accurate Agent Action Reference:
   • Added SelectOption(agentId, value) and GetDropdownOptions(agentId) details.
   • Updated action signatures for PreviousPage and NextPage with optional agentId.
5. Robust Error & State Diagnostics:
   • Added IDLE lifecycle state to page state transitions table.
   • Documented missing SDK error types: JsEvaluationTimeout, ScreenshotFailed, and PageNotReady.
6. Windows Native Build Support: Added optional native package bindings (@rollup/rollup-win32-x64-msvc, lightningcss-win32-x64-msvc, and @tailwindcss/oxide-win32-x64-msvc) to package.json to fix compilation issues on Windows development environments.
