feat: support Ollama, Jan.ai, AnythingLLM, GPT4All & enhance source manager

[albertolicea00]

Summary

This PR adds support for scanning new local LLM sources (Ollama, AnythingLLM, Jan.ai, GPT4All), integrates dynamic application installation detection, and implements hover-friendly quick action buttons to access both local storage folders and official websites. Additionally, it establishes GitHub community standards for the repository.

Key Enhancements

1. New Sources & Graphics Optimization:

   • Integrated scanning support and assets for Ollama, AnythingLLM, Jan.ai, and GPT4All.
   • Optimized source icons in Assets.xcassets to 128x128 resolution.
   • Refactored ParsedModel.Source to hold target settings.

2. Installation Status Detection:

   • Implemented dynamic checks (isInstalled) on ParsedModel.Source to verify if the applications exist in system folders (/Applications / ~/Applications) or if their cache environment is active.
   • Appends a subtle (not installed) badge in secondaryLabelColor next to the checkbox if the app isn't present.

3. Quick Action Shortcuts (Folder & Web):

   • Local Folder Button (📁): Opens the exact scanned directory path ModelPaths.rootPath(for: source) in Finder. It automatically creates the directory if it is missing, making it easy to know where models belong.
   • Web Homepage Button (🌐): Opens the official platform webpage in the default browser.
   • Micro-interactions: Created a lightweight subclass HoverIconButton to handle custom tracking areas, changing the cursor to a pointing hand and highlighting the tint on hover.

4. Community Metadata:

   • Added standard repository documents: LICENSE (MIT), CONTRIBUTING.md, CODE_OF_CONDUCT.md, and SECURITY.md.
   • Set up issue templates for Bug Reports and Feature Requests, along with a Pull Request template under .github/.
   • Updated the README.md to introduce the new source features and display status badges (Platform, Swift, License, Release).

How Has This Been Tested?

• Verified clean build and execution using xcodebuild with Debug configuration under macOS 26.5.1 / Xcode 26.3
• Verified visual row alignments and hover transition effects in the sources section.
