Implements comprehensive Java runtime detection for production environments: * **JavaRuntimeDetector**: Detects JAR files and Java runtime metadata - Scans working directory for .jar files recursively - Extracts versions from JAR manifests and filenames - Collects Java runtime environment information - Generates location-based hashes for change detection * **Runtime Artifact Model**: New schema for deployment artifacts - Uses `type: "runtime"` instead of scope-based model - `artifacts` field contains deployment files (vs dependencies) - `runtime_environment` provides structured platform info - Complements existing dependency model for package managers * **Orchestrator Integration**: Enhanced to handle both models - Supports both `dependencies` and `artifacts` detection - Updated debug output for artifact counting - Maintains backward compatibility * **Comprehensive Testing**: Docker-based integration tests - Tests JAR detection with/without Java runtime - Validates version extraction and metadata collection - Uses eclipse-temurin:17-jre and alpine:latest images * **Complete Documentation**: - Technical detector documentation with examples - Updated project specification with dual models - Test documentation and usage guides Addresses production observability gap where JAR files exist but Maven build tools are unavailable. Establishes foundation for other runtime artifact detectors (Go, Python, Node.js, etc.). 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

How does Syft handle Java environments? TLDR:
Full example output: https://github.com/green-coding-solutions/dependency-resolver/blob/tool-comparison/docs/tool-comparison/kadai/syft-json_formatted.json Dependencies are collected by opening the JAR file as a ZIP and collecting the manifest information. {

Introduces a new detection type "runtime". This makes sense to be able to get information e.g. about the java runtime environment and its artifacts (JAR files). Until now we only had detectors that collected "dependencies".
Marked as draft. Have to be discussed with Arne and Didi.
If it should be added, some more refactorings are required, e.g. changing the parent class of
JavaRuntimeDetectorfromPackageManagerDetectorto a new base classRuntimeDetector.
