Clean up codebase and improve file loading

- Moved plugins to proper sub groups (autopairs, code_minimap, colorize, commentzar, info_bar, markdown_preview, prettify_json, search_replace, tabs_bar, telescope, toggle_source_view, lsp_client)
- Add filter_out_loaded_files to prevent opening already-loaded files
- Add INDEPENDENT source view state
- Fix cursor scroll position on buffer switch
- Fix signal blocking during file load
- Fix word boundary in completion provider
- Refactor code events into single events module
