Add comment to CI skip check job

- Simplify the CI workflow by consolidating the skip check for both branch names and commit messages to a single case-insensitive pattern: @skipci.
- Remove the previous multiple pattern checks to streamline the logic and improve readability.
- Ensure that the CI process can be effectively skipped based on the new pattern, enhancing overall efficiency.

+# Timeshift Snapshot and Rollback Guide
+
+## Overview
+
+Timeshift is a system restore utility that creates snapshots of your system before Ansible playbook execution.
+This allows you to easily rollback if something goes wrong during configuration changes.
+
+## How It Works
+
+When you run a playbook, the Timeshift role automatically:
+1. Checks if Timeshift is installed (installs if missing)
+2. Creates a snapshot before making any changes
+3. Tags the snapshot with "ansible" and "pre-playbook" for easy identification
+
+## Usage
+
+### Automatic Snapshots
+
+Snapshots are created automatically when running playbooks:
+
+```bash
+# Run playbook - snapshot created automatically
+make dev HOST=dev02
+
+# Or run only snapshot creation
+make timeshift-snapshot HOST=dev02
+```
+
+### List Snapshots
+
+```bash
+# List all snapshots on a host
+make timeshift-list HOST=dev02
+
+# Or manually on the host
+ssh ladmin@192.168.20.28 "sudo timeshift --list"
+```
+
+### Restore from Snapshot
+
+```bash
+# Restore from a specific snapshot
+make timeshift-restore HOST=dev02 SNAPSHOT=2025-12-17_21-30-00
+
+# The command will:
+# 1. Show available snapshots if SNAPSHOT is not provided
+# 2. Ask for confirmation before restoring
+# 3. Restore the system to that snapshot
+```
+
+### Manual Snapshot
+
+```bash
+# Create snapshot manually on host
+ssh ladmin@192.168.20.28
+sudo timeshift --create --comments "Manual snapshot before manual changes"
+```
+
+### Manual Restore
+
+```bash
+# SSH to host
+ssh ladmin@192.168.20.28
+
+# List snapshots
+sudo timeshift --list
+
+# Restore (interactive)
+sudo timeshift --restore
+
+# Or restore specific snapshot (non-interactive)
+sudo timeshift --restore --snapshot '2025-12-17_21-30-00' --scripted
+```
+
+## Configuration
+
+### Disable Auto-Snapshots
+
+If you don't want automatic snapshots, disable them in `host_vars` or `group_vars`:
+
+```yaml
+# inventories/production/host_vars/dev02.yml
+timeshift_auto_snapshot: false
+```
+
+### Customize Snapshot Settings
+
+```yaml
+# inventories/production/group_vars/dev/main.yml
+timeshift_snapshot_description: "Pre-deployment snapshot"
+timeshift_snapshot_tags: ["ansible", "deployment"]
+timeshift_keep_daily: 7
+timeshift_keep_weekly: 4
+timeshift_keep_monthly: 6
+```
+
+## Important Notes
+
+### Disk Space
+
+- Snapshots require significant disk space (typically 10-50% of system size)
+- RSYNC snapshots are larger but work on any filesystem
+- BTRFS snapshots are smaller but require BTRFS filesystem
+- Monitor disk usage: `df -h /timeshift`
+
+### What Gets Backed Up
+
+By default, Timeshift backs up:
+- ✅ System files (`/etc`, `/usr`, `/boot`, etc.)
+- ✅ System configuration
+- ❌ User home directories (`/home`) - excluded by default
+- ❌ User data
+
+### Recovery Process
+
+1. **Boot from recovery** (if system won't boot):
+   - Boot from live USB
+   - Install Timeshift: `sudo apt install timeshift`
+   - Run: `sudo timeshift --restore`
+
+2. **Restore from running system**:
+   - SSH to host
+   - Run: `sudo timeshift --restore`
+   - Select snapshot and confirm
+
+### Best Practices
+
+1. **Always create snapshots before major changes**
+   ```bash
+   make timeshift-snapshot HOST=dev02
+   make dev HOST=dev02
+   ```
+
+2. **Test rollback process** before you need it
+   ```bash
+   # Create test snapshot
+   make timeshift-snapshot HOST=dev02
+   
+   # Make a test change
+   # ...
+   
+   # Practice restoring
+   make timeshift-list HOST=dev02
+   make timeshift-restore HOST=dev02 SNAPSHOT=<test-snapshot>
+   ```
+
+3. **Monitor snapshot disk usage**
+   ```bash
+   ssh ladmin@192.168.20.28 "df -h /timeshift"
+   ```
+
+4. **Clean up old snapshots** if needed
+   ```bash
+   ssh ladmin@192.168.20.28 "sudo timeshift --delete --snapshot 'OLD-SNAPSHOT'"
+   ```
+
+## Troubleshooting
+
+### Snapshot Creation Fails
+
+```bash
+# Check Timeshift status
+ssh ladmin@192.168.20.28 "sudo timeshift --list"
+
+# Check disk space
+ssh ladmin@192.168.20.28 "df -h"
+
+# Check Timeshift logs
+ssh ladmin@192.168.20.28 "sudo journalctl -u timeshift"
+```
+
+### Restore Fails
+
+- Ensure you have enough disk space
+- Check that snapshot still exists: `sudo timeshift --list`
+- Try booting from recovery media if system won't boot
+
+### Disk Full
+
+```bash
+# List snapshots
+sudo timeshift --list
+
+# Delete old snapshots
+sudo timeshift --delete --snapshot 'OLD-SNAPSHOT'
+
+# Or configure retention in group_vars
+timeshift_keep_daily: 3  # Reduce from 7
+timeshift_keep_weekly: 2  # Reduce from 4
+```
+
+## Integration with Ansible
+
+The Timeshift role is automatically included in the development playbook and runs first to create snapshots before any changes are made.
+This ensures you always have a restore point.
+
+```yaml
+# playbooks/development.yml
+roles:
+  - {role: timeshift, tags: ['timeshift', 'snapshot']}  # Runs first
+  - {role: base}
+  - {role: development}
+  # ... other roles
+```

+# Timeshift Role
+
+Manages Timeshift system snapshots for backup and rollback capabilities.
+
+## Purpose
+
+This role installs and configures Timeshift, a system restore utility for Linux. It can automatically create snapshots before playbook execution to enable easy rollback if something goes wrong.
+
+## Features
+
+- Installs Timeshift package
+- Creates automatic snapshots before playbook runs
+- Configurable snapshot retention
+- Easy rollback capability
+
+## Variables
+
+### Installation
+- `timeshift_install` (default: `true`) - Install Timeshift package
+
+### Snapshot Settings
+- `timeshift_auto_snapshot` (default: `true`) - Automatically create snapshot before playbook execution
+- `timeshift_snapshot_description` (default: `"Ansible playbook snapshot"`) - Description for snapshots
+- `timeshift_snapshot_tags` (default: `["ansible", "pre-playbook"]`) - Tags for snapshots
+- `timeshift_snapshot_type` (default: `"RSYNC"`) - Snapshot type: RSYNC or BTRFS
+
+### Retention
+- `timeshift_keep_daily` (default: `7`) - Keep daily snapshots for N days
+- `timeshift_keep_weekly` (default: `4`) - Keep weekly snapshots for N weeks
+- `timeshift_keep_monthly` (default: `6`) - Keep monthly snapshots for N months
+
+### Location
+- `timeshift_snapshot_location` (default: `"/timeshift"`) - Where to store snapshots
+
+## Usage
+
+### Basic Usage
+
+Add to your playbook:
+```yaml
+roles:
+  - { role: timeshift, tags: ['timeshift', 'snapshot'] }
+```
+
+### Disable Auto-Snapshot
+
+```yaml
+roles:
+  - { role: timeshift, tags: ['timeshift'] }
+```
+
+In host_vars or group_vars:
+```yaml
+timeshift_auto_snapshot: false
+```
+
+### Manual Snapshot
+
+```bash
+# On the target host
+sudo timeshift --create --comments "Manual snapshot before changes"
+```
+
+### Rollback
+
+```bash
+# List snapshots
+sudo timeshift --list
+
+# Restore from snapshot
+sudo timeshift --restore --snapshot 'YYYY-MM-DD_HH-MM-SS'
+
+# Or use the Makefile target
+make timeshift-restore HOST=dev02 SNAPSHOT=2025-12-17_21-30-00
+```
+
+## Integration with Playbooks
+
+The role is designed to be run early in playbooks to create snapshots before making changes:
+
+```yaml
+roles:
+  - { role: timeshift, tags: ['timeshift', 'snapshot'] }  # Create snapshot first
+  - { role: base }
+  - { role: development }
+  # ... other roles
+```
+
+## Dependencies
+
+- Debian/Ubuntu-based system
+- Root/sudo access
+
+## Notes
+
+- Snapshots require significant disk space
+- RSYNC snapshots are larger but work on any filesystem
+- BTRFS snapshots are smaller but require BTRFS filesystem
+- Snapshots exclude `/home` by default (configurable)
+
