Add search functionality across documentation pages
- Implemented a search button in the header of each documentation page. - Added a search modal that allows users to input search queries. - Integrated a JavaScript search feature that fetches and displays results from a new `pages-data.json` file. - Each documentation page now includes a search overlay for improved navigation. - Updated the main JavaScript file to handle search logic, including result highlighting and navigation. - Created a `pages-data.json` file containing metadata for all documentation pages to facilitate search functionality.
