Update documentation: CHANGELOG and QUICKSTART

Updated documentation to reflect the complete feature set:

CHANGELOG.md updates:
- Updated test count from 52 to 70 tests across 9 test classes
- Updated coverage from 45% to 39% (added more code, focus on API contracts)
- Added NativeProcessLauncher and ContainerLauncher to test list
- Added new Documentation section listing:
  - NATIVE_EXECUTION.md guide
  - CONTAINER_DEPLOYMENT.md guide
  - jplatform-core/README.md module docs
  - Updated main README.md
  - Complete Javadoc for all new classes

QUICKSTART.md updates:
- Added new "Deployment Modes" section with three modes:
  1. JVM Applications (default)
  2. Native Processes (GraalVM, compiled binaries)
  3. Containers (Docker/Podman/LXC)
- Example YAML descriptors for each deployment mode
- Links to detailed documentation (NATIVE_EXECUTION.md, CONTAINER_DEPLOYMENT.md)
- Updated "Next Steps" section with links to new guides

All documentation now accurately reflects:
- 70 unit tests (all passing)
- Three deployment modes supported
- Complete feature documentation
- Javadoc coverage on all classes

+## Deployment Modes
+
+JPlatform supports three deployment modes:
+
+### 1. JVM Applications (Default)
+
+Standard Java applications running in isolated classloaders:
+
+```yaml
+applicationId: my-java-app
+mainClass: com.example.MyApp
+classpathEntries:
+  - file:///path/to/app.jar
+```
+
+### 2. Native Processes
+
+Deploy GraalVM native images or compiled executables:
+
+```yaml
+applicationId: graal-app
+nativeImage: true
+classpathEntries:
+  - file:///usr/local/bin/myapp
+
+properties:
+  native.args: "--server --port=8080"
+  native.env.DATABASE_URL: "jdbc:postgresql://db/app"
+  native.workdir: "/var/apps/graal-app"
+```
+
+See [NATIVE_EXECUTION.md](NATIVE_EXECUTION.md) for details.
+
+### 3. Containers
+
+Deploy applications as Docker, Podman, or LXC containers:
+
+```yaml
+applicationId: web-server
+properties:
+  container.runtime: docker
+  container.image: nginx:alpine
+  container.ports: "8080:80,8443:443"
+  container.volumes: "/var/www:/usr/share/nginx/html"
+  container.network: bridge
+  container.env.NGINX_HOST: example.com
+```
+
+See [CONTAINER_DEPLOYMENT.md](CONTAINER_DEPLOYMENT.md) for details.
