Subject: [PATCH] refactor: remove dead PLGX-related code

- Remove PluginPackageFormat.Plgx; only DLL format is supported.

- Remove PLGX detection from PluginPathResolver.

- Remove PLGX asset URL handling from UpdateChecker.

- Remove PLGX tests; dotnet test passes 51/51.

- Remove *.plgx from .gitignore.

Closes #35.
