Add TanStack Start framework detection with package-based detection support

[Copilot]

Overview

This PR adds support for detecting TanStack Start framework and introduces a new architecture for package-based framework detection. TanStack Start doesn't have specific configuration files like other frameworks, so detection relies on checking for the @tanstack/react-start package in package.json.

Motivation

TanStack Start is a modern full-stack React framework that requires detection for proper build configuration. Unlike frameworks such as Next.js or Nuxt that have distinctive config files (next.config.js, nuxt.config.js), TanStack Start projects are identified solely by their dependency on @tanstack/react-start.

Key Changes

1. Architecture Refactoring

Introduced typed input system with addInput() method:

// Before
$detector = new Framework(['file1.js', 'file2.js'], 'npm');

// After  
$detector = new Framework('npm');
$detector->addInput('path', 'file1.js');
$detector->addInput('path', 'file2.js');
$detector->addInput('packages', $packageJsonContent);

This provides:

• Type-safe input validation
• Support for different input types (path, packages, language, extension)
• Better extensibility for future enhancements
• Cleaner separation of concerns

2. Framework Detection Enhancement

Added package-based detection:

• New getPackages() method in Framework base class (returns empty array by default)
• Framework detector now checks both file patterns and package names
• Input type validation with InvalidArgumentException for Framework detector (only accepts 'path' and 'packages')

TanStack Start framework class:

• Detects via @tanstack/react-start package
• Supports npm, yarn, and pnpm package managers
• Build output: ./dist
• Install: npm install, yarn install, or pnpm install
• Build: npm run build, yarn build, or pnpm build

3. SSR Detection

Added TanStack Start to SSR detection with server/index.mjs as the indicator file, consistent with other frameworks like Nuxt and Analog.

4. Comprehensive Test Updates

• Updated all existing tests to use the new addInput() API
• Added TanStack Start-specific test cases:
  • Package-based detection (dependencies and devDependencies)
  • Input type validation
  • SSR and static rendering detection

Usage Example

use Utopia\Detector\Detector\Framework;
use Utopia\Detector\Detection\Framework\TanStackStart;

$detector = new Framework('npm');
$detector->addOption(new TanStackStart());

// Read and pass package.json content
$packageJson = file_get_contents('package.json');
$detector->addInput('packages', $packageJson);

$framework = $detector->detect();
if ($framework && $framework->getName() === 'tanstack-start') {
    echo $framework->getInstallCommand(); // "npm install"
    echo $framework->getBuildCommand();   // "npm run build"
    echo $framework->getOutputDirectory(); // "./dist"
}

Breaking Changes

⚠️ This introduces breaking changes to the detector API:

• All detector constructors have changed (no longer accept inputs as first parameter)
• Code using detectors must migrate to use addInput() method
• Tests must be updated to use the new API

The new API provides better type safety, more flexibility, and cleaner code organization that will benefit future enhancements.

Testing

All functionality has been validated:

• ✅ TanStack Start detection via package.json
• ✅ Traditional path-based framework detection still works
• ✅ SSR detection for TanStack Start
• ✅ Input type validation
• ✅ All existing detector tests updated and passing
• ✅ No security vulnerabilities (CodeQL passed)

Original prompt

In framework detection, add support for TanStack Start. It doesn't have specific file that indicates it, but inside package.json it will always include @tanstack/react-start. Introduce proper methods following existing standards and adapter approach to be able to provide contents of package.json when doing framework detection. Do this by removing $inputs from inputs, and instead, have method addInput. here accept not only intput content, but also it's type. Then in Framework.php detection override this method to only allow "path" and "packages" types. Now to detect Tanstack Start, look only for "packages" type inputs, and in them, look for @tanstack/react-start text.

In rendering detection, add support to SSR detection to consider "server/index.mjs" as SSR in tanstack start.

Implement tests for all changes.
