Summary

Adds an LM Studio translator endpoint for local OpenAI-compatible chat completion servers, proposes adopting the MIT License, and refreshes the README.

This lets users run translations through LM Studio's local server, which can be faster for local workflows and avoids routing requests through external hosted APIs.

Changes

• Add LmStudioTranslate endpoint using LM Studio's default OpenAI-compatible /v1/chat/completions API.
• Add LmStudio.yaml sample configuration.
• Document LM Studio setup and endpoint selection in the README.
• Add config tests for the LM Studio sample.
• Fix glossary prompt override loading so *-GlossaryPrompt.txt updates GlossaryPrompt.
• Update ILRepack packaging so release builds merge only YamlDotNet and work with current .NET SDK tooling.
• Add a standard MIT LICENSE file using joshfreitas1984 and contributors as the copyright holder line.
• Add PackageLicenseExpression=MIT to the plugin project metadata.
• Refresh the README structure for supported endpoints, installation, configuration, override files, glossary behavior, prompt tuning, build/test commands, and current project notes.

License note

The upstream repository currently does not expose a detected license through GitHub metadata. This PR proposes adopting MIT so users and contributors have explicit permission terms for use, modification, and redistribution.

Validation

• git diff --check
• dotnet restore XUnity.AutoTranslate.LlmTranslators.sln
• dotnet build XUnity.AutoTranslate.LlmTranslators.sln -c Debug --no-restore
• dotnet build XUnity.AutoTranslate.LlmTranslators.sln -c Release --no-restore
• dotnet test XUnity.AutoTranslate.LlmTranslators.sln -c Release --no-build --filter "FullyQualifiedName!~PromptTests"

Note: PromptTests were excluded because they can call live OpenAI/Ollama/LM Studio endpoints.

Known warning: restore/build still reports the existing high-severity advisory for YamlDotNet 4.2.1.
