Add IDE clone links and download ZIP features to repository detail page

[Copilot]

Overview

This PR adds direct cloning links for popular IDEs and a download ZIP button to the repository detail page, making it easier for users to clone repositories directly into their preferred development environment.

Problem

Previously, users could only copy the Git URL and manually paste it into their IDE's clone dialog. This required multiple steps and was not user-friendly, especially for users who frequently work with multiple repositories.

Solution

Added three new features to the repository detail page:

1. "Open with" Dropdown Menu

A dropdown button that provides direct links to clone the repository in 18 popular IDEs:

• Microsoft: Visual Studio, Visual Studio Code
• JetBrains: IntelliJ IDEA, PyCharm, WebStorm, PhpStorm, Rider, CLion, DataGrip, GoLand, RubyMine, AppCode, Fleet, RustRover, Aqua
• Other: Android Studio, Eclipse, Tower

Each IDE uses its specific protocol handler (e.g., vscode://vscode.git/clone?url={url} for VS Code, jetbrains://idea/git-clone?url={url} for IntelliJ) to open the IDE directly with the repository URL pre-filled.

2. Download ZIP Button

A direct link to download the entire repository as a ZIP file, useful for quick access without cloning.

3. User IDE Preference

Added a "Preferred IDE" setting in Account Settings where users can save their default IDE choice for future reference.

Screenshots

Repository Detail Page - Initial View

The page now shows "Open with" and "Download ZIP" buttons next to the Git URL copy button.

IDE Selection Dropdown

Clicking "Open with" displays all 18 supported IDEs. Selecting one opens the IDE with the clone URL.

Technical Details

New Components

• Configuration/IdeType.cs: Enum defining all supported IDE types
• Helpers/IdeHelper.cs: Helper methods for IDE display names and protocol URL generation
• wwwroot/js/ide-dropdown.js: JavaScript for dropdown menu interaction
• Database migrations: Added PreferredIde column to UserSettings table for both SQLite and SQL Server

Modified Components

• Extended UserSettings, UserSettingsEntity, and UserSettingsService to handle IDE preferences
• Updated MeSettingsModel and Account Settings view to include IDE selection
• Enhanced Detail.cshtml with IDE dropdown and Download ZIP button
• Added localized resource strings for new UI elements
• Added CSS styles for the dropdown menu

Protocol Handlers

• Visual Studio: git-client://clone?repo={url}
• VS Code: vscode://vscode.git/clone?url={url}
• JetBrains IDEs: jetbrains://{ide}/git-clone?url={url}
• Tower: gittower://openRepo/{url}
• Eclipse: Standard Git URL (no custom protocol)

Testing

• ✅ Build successful with 0 errors
• ✅ All 237 unit tests pass
• ✅ All 17 integration tests pass
• ✅ No breaking changes to existing functionality
• ✅ Backward compatible (PreferredIde defaults to None)

Usage

Users can now:

1. Navigate to any repository detail page
2. Click "Open with" to see available IDE options
3. Select their preferred IDE to clone directly
4. Click "Download ZIP" to download the repository
5. Set their default IDE in Account Settings for future reference

Notes

• The feature works for both public Git URLs and personal (authenticated) URLs
• All existing functionality (copy button, repository management) remains unchanged
• The implementation follows existing UI patterns and coding standards
• Database migrations are included and will run automatically on deployment
