- Remove the enableAniSkipStateProvider check, because it is already being checked by the caller (anime_player_view.dart, initState() line 353).
- Change ref.watch() to ref.read() as the user cannot change its value without exiting the video player. ref.watch() is meant to be used within reactive contexts.
Collapse three `.position.listen` callbacks into a single
subscription to reduce per‑tick overhead and centralize all
position‑driven updates (current position, subtitle/audio init,
and skip‑phase logic) in one handler.
The variables `enableAniSkip`, `enableAutoSkip`,
`aniSkipTimeoutLength` and `skipIntroLength` are global settings.
The user cannot change them inside the video player.
So there's no need to watch them inside the _currentPosition listener.
fixed UTF8 bug
fixed infinite loading
added search bar to migration screen
migration screen now considers the pinned sources option
library now shows if the items are locally tracked or not
Before fixing the Category Removal Bug (commit 58537281), the "Default" Category would be empty when removing a populated category.
So when there is only one Category left, and the user hides that one Category, `tabCount` would be <= 0, leading to an Exception:
```
_AssertionError ('package:flutter/src/material/tab_controller.dart': Failed assertion: line 116 pos 15: 'initialIndex >= 0 && (length == 0 || initialIndex < length)': is not true.)
```
Now there is a check (`tabCount <= 0`), that IF tabCount is ever <= 0, it would show `_bodyWithoutCategories`.
When removing a category, the items inside the category were not being updated, removing the link to the removed category.
That lead to the items disappearance from the library.
Now the reference from the item to the deleted category is deleted. Those items show up in the "Default" category.
