feat(event-watchers): rework file state detection and migrate tree-sitter integration

Switch file state checks to trigger on FocusedViewEvent instead of TextChangedEvent
Resolve file via files controller and operate directly on file object
Add user prompt for externally modified files with optional reload
Auto-reload unmodified buffers when external changes are detected
Simplify file_is_deleted / file_is_externally_modified APIs

tree-sitter

Remove bundled tree_sitter_language_pack and related setup/notes scripts
Introduce local lightweight tree_sitter wrapper (Parser, get_parser)
Store parser per file and generate AST directly from buffer text
Remove runtime language download/config logic
Update manifest (drop autoload)

core

Simplify CLI file handling in BaseControllerMixin
Send directory args directly via IPC instead of encoding in file list

cleanup

Remove unused libs, scripts, and legacy code paths

-# Python-With-Gtk-Template
-A template project for Python with Gtk applications.
-
-### 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)
+# Newton
+A Python + Gtk 3 based quasi-IDE.
 
 ### 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.
-* 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
+[TODO](TODO.md)
 
-
-For the user_config, after changing names and files, copy all content to their respective destinations.
-The logic follows Debian Dpkg packaging and its placement logic.
