Thorrent qBit Plugin Browser - v0.9.98.5

Purpose
-------
Plugin Browser is the catalog side of qBit Plugin Lab.

Installed Plugins:
- Shows local .py search plugins in data\plugins\qbit\engines\
- Lets you enable/disable plugins without renaming files
- Runs only enabled plugins during qBit Plugin Lab searches

Plugin Browser:
- Fetches the qBittorrent unofficial plugin wiki catalog
- Shows available community plugins
- Shows installed/enabled status
- Downloads plugin .py files into data\plugins\qbit\engines\
- Installs downloaded plugins DISABLED by default
- Can remove installed plugins by moving them into data\plugins\qbit\removed\

Safety
------
qBittorrent-style search plugins are Python scripts. They are not automatically safe.
Thorrent runs searches in subprocesses with timeout protection, but this is not a
full security sandbox. Use audited plugins only.

Recommended workflow
--------------------
1. Open qBit Plugin Lab.
2. Open Plugin Browser.
3. Click Refresh Catalog.
4. Select a plugin.
5. Download it.
6. Review/test it.
7. Enable it if it works.
8. Disable/remove broken plugins.

Notes
-----
Some catalog plugins are old, broken, private-site-only, Cloudflare-sensitive,
or require manual editing/API keys. Warnings from the catalog are shown when
possible, but Thorrent cannot guarantee plugin safety or reliability.
