ansible eba1a05e7d Implement critical role improvements per ROLE_ANALYSIS_AND_IMPROVEMENTS.md 
This commit addresses the critical issues identified in the role analysis:

## Security Improvements

### Remove Hardcoded Secrets (deploy_linux_vm)
- Replaced hardcoded SSH key in defaults/main.yml with vault variable reference
- Replaced hardcoded root password with vault variable reference
- Created vault.yml.example to document secret structure
- Updated README.md with comprehensive security best practices section
- Added documentation for Ansible Vault, external secret managers, and environment variables
- Included SSH key generation and password generation best practices

## Role Documentation & Planning

### CHANGELOG.md Files
- Created comprehensive CHANGELOG.md for deploy_linux_vm role
  - Documented v1.0.0 initial release features
  - Tracked v1.0.1 security improvements
- Created comprehensive CHANGELOG.md for system_info role
  - Documented v1.0.0 initial release
  - Tracked v1.0.1 critical bug fixes (block-level failed_when, Jinja2 templates, OS variables)

### ROADMAP.md Files
- Created detailed ROADMAP.md for deploy_linux_vm role
  - Version 1.1.0: Security & compliance hardening (Q1 2026)
  - Version 1.2.0: Multi-distribution support (Q2 2026)
  - Version 1.3.0: Advanced features (Q3 2026)
  - Version 2.0.0: Enterprise features (Q4 2026)
- Created detailed ROADMAP.md for system_info role
  - Version 1.1.0: Enhanced monitoring & metrics (Q1 2026)
  - Version 1.2.0: Cloud & container support (Q2 2026)
  - Version 1.3.0: Hardware & firmware deep dive (Q3 2026)
  - Version 2.0.0: Visualization & reporting (Q4 2026)

## Error Handling Enhancements

### deploy_linux_vm Role - Block/Rescue/Always Pattern
- Wrapped deployment tasks in comprehensive error handling block
- Block section:
  - Pre-deployment VM name collision check
  - Enhanced IP address acquisition with better error messages
  - Descriptive failure messages for troubleshooting
- Rescue section (automatic rollback):
  - Diagnostic information gathering
  - VM status checking
  - Attempted console log capture
  - Automatic VM destruction and cleanup
  - Disk image removal (primary, LVM, cloud-init ISO)
  - Detailed troubleshooting guidance
- Always section:
  - Deployment logging to /var/log/ansible-vm-deployments.log
  - Success/failure tracking
- Improved task FQCNs (ansible.builtin.*)

## Handlers Implementation

### deploy_linux_vm Role - Complete Handler Suite
- VM Lifecycle Handlers:
  - restart vm, shutdown vm, destroy vm
- Cloud-Init Handlers:
  - regenerate cloud-init iso (full rebuild and reattach)
- Storage Handlers:
  - refresh libvirt storage pool
  - resize vm disk (with safe shutdown/start)
- Network Handlers:
  - refresh network configuration
  - restart libvirt network
- Libvirt Daemon Handlers:
  - restart libvirtd, reload libvirtd
- Cleanup Handlers:
  - cleanup temporary files
  - remove cloud-init iso
- Validation Handlers:
  - validate vm status
  - check connectivity

## Impact

### Security
- Eliminates hardcoded secrets from version control
- Implements industry best practices for secret management
- Provides clear guidance for secure deployment

### Maintainability
- CHANGELOGs enable version tracking and change auditing
- ROADMAPs provide clear development direction and prioritization
- Comprehensive error handling reduces debugging time
- Handlers enable modular, reusable state management

### Reliability
- Automatic rollback prevents partial deployments
- Comprehensive error messages reduce MTTR
- Handlers ensure consistent state management
- Better separation of concerns

### Compliance
- Aligns with CLAUDE.md security requirements
- Implements proper secrets management per organizational policy
- Provides audit trail through changelogs
