feat(examples): add deployment examples for common use cases

Add 5 example configurations covering popular deployment scenarios:

1. minimal.yaml - Quick start with ephemeral storage
2. production.yaml - Production setup with PVC and resource limits
3. hardware-acceleration.yaml - GPU transcoding (Intel QuickSync)
4. ingress-tls.yaml - External access with HTTPS and cert-manager
5. network-policy.yaml - Secure deployment with network isolation

Includes comprehensive README explaining usage and combinations.

+# Jellyfin Helm Chart Examples
+
+This directory contains example configurations for common Jellyfin deployment scenarios.
+
+## Available Examples
+
+### 1. Minimal (`minimal.yaml`)
+
+Quick start configuration with ephemeral storage for testing purposes.
+
+```bash
+helm install jellyfin jellyfin/jellyfin -f examples/minimal.yaml
+```
+
+**Use case**: Development, testing, demo environments.
+
+**Note**: All data will be lost when the pod is restarted.
+
+---
+
+### 2. Production (`production.yaml`)
+
+Production-ready configuration with persistent storage, resource limits, and optimized health probes.
+
+```bash
+helm install jellyfin jellyfin/jellyfin -f examples/production.yaml
+```
+
+**Features**:
+
+- Persistent storage for config, media, and cache
+- Resource requests and limits
+- Optimized health probes for large libraries
+- Security context with non-root user
+
+---
+
+### 3. Hardware Acceleration (`hardware-acceleration.yaml`)
+
+Enable GPU acceleration for video transcoding (Intel QuickSync example).
+
+```bash
+helm install jellyfin jellyfin/jellyfin -f examples/hardware-acceleration.yaml
+```
+
+**Prerequisites**:
+
+- Node with compatible GPU (Intel/AMD/NVIDIA)
+- GPU device plugin installed in cluster
+- Appropriate node labels/taints
+
+**Note**: Adjust device paths and capabilities for your specific GPU type. See [Jellyfin documentation](https://jellyfin.org/docs/general/administration/hardware-acceleration/) for details.
+
+---
+
+### 4. Ingress with TLS (`ingress-tls.yaml`)
+
+External access via HTTPS with automatic certificate management.
+
+```bash
+helm install jellyfin jellyfin/jellyfin -f examples/ingress-tls.yaml
+```
+
+**Prerequisites**:
+
+- Ingress controller (e.g., ingress-nginx)
+- cert-manager for automatic TLS certificates (optional)
+- DNS record pointing to your cluster
+
+**Configuration**:
+
+- Update `jellyfin.example.com` to your actual domain
+- Adjust cert-manager issuer if using different CA
+
+---
+
+### 5. NetworkPolicy Security (`network-policy.yaml`)
+
+Secure deployment with network isolation and controlled traffic flow.
+
+```bash
+helm install jellyfin jellyfin/jellyfin -f examples/network-policy.yaml
+```
+
+**Prerequisites**:
+
+- CNI plugin with NetworkPolicy support (Calico, Cilium, Weave, Canal)
+- Ingress controller with known namespace/labels
+
+**Features**:
+
+- Restrict ingress to Ingress controller only
+- Allow egress for DNS and metadata providers (HTTPS/443)
+- Block unrestricted pod-to-pod communication
+
+---
+
+## Combining Examples
+
+You can combine multiple example files to create custom configurations:
+
+```bash
+helm install jellyfin jellyfin/jellyfin \
+  -f examples/production.yaml \
+  -f examples/hardware-acceleration.yaml \
+  -f examples/ingress-tls.yaml
+```
+
+Files are merged in order, with later files overriding earlier ones.
+
+## Custom Values
+
+All examples can be further customized by overriding specific values:
+
+```bash
+helm install jellyfin jellyfin/jellyfin \
+  -f examples/production.yaml \
+  --set persistence.media.size=1Ti \
+  --set resources.limits.memory=16Gi
+```
