Add more built-in output schemas for common operations

[initcron]

Overview

Currently we have 4 built-in output schemas:

• container-list - Docker/K8s container listings
• resource-stats - Resource usage statistics
• simple-list - Simple string lists
• key-value - Key-value data

Proposed Additional Schemas

Docker/Container Operations

• docker-images - Docker image listings with size, tags, created date
• docker-networks - Docker network information
• docker-volumes - Docker volume listings

Kubernetes Operations

• k8s-pods - Pod listings with status, restarts, age
• k8s-services - Service listings with type, cluster-IP, ports
• k8s-deployments - Deployment status with replicas
• k8s-nodes - Node information with capacity and conditions

System Operations

• process-list - Running processes with CPU, memory, PID
• file-list - File/directory listings with size, permissions, date
• disk-usage - Disk space usage by mount point

Cloud Operations

• aws-instances - EC2 instance listings
• aws-s3-buckets - S3 bucket listings
• gcp-instances - GCP VM instances
• azure-vms - Azure VM listings

Database Operations

• db-tables - Database table listings
• db-query-results - Query result sets

Log/Event Operations

• log-entries - Structured log entries with timestamp, level, message
• event-timeline - Timeline of events

Implementation

Each schema should:

1. Be added to crates/aof-core/src/schema.rs in the schemas module
2. Have appropriate FormatHint (Table, List, etc.)
3. Include description and validation
4. Be documented with examples
