Temporarily disable plugin manager, pending some bugfixes:
- Startup time: Maybe refreshing plugins at startup?
- Debug logging: Is rather verbose in debug output
- Allows running the following from the command palette (Ctrl+;)
- Update All Plugins: Updates all plugins
- List All Plugins: Lists all installed plugins
- Add user customization via automatically detected user.lua file
- Reorganize config options into separate files
- Reorganize plugin loaders into separate files
