Review repository for improvement opportunities - #2
Conversation
This commit enhances all Kubernetes manifests with production best practices: **Reliability & Health** - Add liveness and readiness probes to all deployments - Enable automatic pod restarts on failures - Add resource requests for proper pod scheduling - Add resource limits to prevent resource exhaustion **Autoscaling** - Upgrade HPAs from v1 to v2 for advanced features - Add memory-based autoscaling alongside CPU - Configure smart scaling policies (fast scale-up, gradual scale-down) - Fix testcpu-hpa to allow actual scaling (was min=max=1) **Organization & Maintainability** - Remove runtime state from web-deployment.yaml - Add consistent labels (app, component, version) across all resources - Add explicit namespaces to all resources - Name ports in services for better observability - Add imagePullPolicy: Always for latest tag management **Documentation & Tooling** - Comprehensive README with architecture diagram - Add Makefile for simplified deployment workflow - Add .gitignore to prevent committing sensitive files - Document resource allocations and monitoring commands **Resource Specifications** - Web: 100m/500m CPU, 128Mi/512Mi memory - API: 200m/1000m CPU, 256Mi/1Gi memory - Crawler (per container): 100m/500m CPU, 128Mi/512Mi memory - Test workloads: Right-sized for testing scenarios These changes ensure reliable deployments, better resource utilization, and easier maintenance while following Kubernetes best practices.

Pull Request Overview
This PR enhances the Kubernetes manifests with production-ready best practices including health monitoring, resource management, and autoscaling capabilities. The changes improve reliability, observability, and operational efficiency of the SynergyChat application stack.
Key changes:
- Upgraded HPAs from v1 to v2 with memory-based autoscaling and intelligent scaling policies
- Added comprehensive health probes (liveness/readiness) to all deployments
- Configured resource requests/limits across all workloads to ensure proper scheduling and prevent resource exhaustion

[nitpick] The liveness probe uses tcpSocket while the first crawler container (synergychat-crawler-1) uses httpGet. For consistency and better health checking, consider using httpGet on path / for crawler-2's liveness probe as well, similar to crawler-1.

[nitpick] The readiness probe uses tcpSocket while the first crawler container uses httpGet. For consistency, consider using httpGet on path / for crawler-2's readiness probe to match the pattern used in crawler-1.
