Fix unload lifecycle, widget cleanup, and plugin removal handling

- Rename GodotHandler to GDScriptHandler in LSP client
- Fix unload() method naming in nanoesq_temp_buffer plugin
- Return manifest_meta in manifest_manager for manual launch plugins
- Properly destroy tabs_widget, viewport, and scrolled_win on unload
- Refactor plugin removal to search all manifest lists and fix cleanup order
- Fix widget reference in plugins_ui (use child instead of box)

-# Python-With-Gtk-Template
+# Newton
-A template project for Python with Gtk applications.
+A Python + Gtk 3 based quasi-IDE.
-
-### Requirements
-* PyGObject (Gtk introspection library)
-* pygobject-stubs (For actually getting pylsp or python-language-server to auto complete in LSPs. Do if GTK3 --no-cache-dir --config-settings=config=Gtk3,Gdk3,Soup2)
-* pyxdg (Desktop ".desktop" file parser)
-* setproctitle (Define process title to search and kill more easily)
-* sqlmodel (SQL databases and is powered by Pydantic and SQLAlchemy)
 
 ### Note
-* pyrightconfig.json can prompt IDEs that use pyright lsp on where imports are located- look at venvPath and venv. "venvPath" is parent path of "venv" where "venv" is just the name of the folder under the parent path that is the python created venv.
+[TODO](TODO.md)
-* Move respetive sub folder content under user_config to the same places in Linux. Though, user/share/<app name> can go to ~/.config folder if prefered.
-* In additiion, place the plugins folder in the same app folder you moved to /usr/share/<app name> or ~/.config/<app name> .
-There are a "\<change_me\>" strings and files that need to be set according to your app's name located at:
-* \_\_builtins\_\_.py
-* user_config/bin/app_name
-* user_config/usr/share/app_name
-* user_config/usr/share/app_name/icons/app_name.png
-* user_config/usr/share/app_name/icons/app_name-64x64.png
-* user_config/usr/share/applications/app_name.desktop
 
-
+### Images
-For the user_config, after changing names and files, copy all content to their respective destinations.
+![1 Newton default view.](images/pic1.png)
-The logic follows Debian Dpkg packaging and its placement logic.
+![2 Newton split pane view.](images/pic2.png)
+![3 Newton search and replace shown.](images/pic3.png)
+![4 Newton displaying inline colors.](images/pic4.png)
+![5 Newton as transparent with youtube playing below it.](images/pic5.png)
+![6 Newton with plugins menu show as well as markdown preview shown.](images/pic6.png)
