fix: correct version injection in build process

• Add SourceFile field to SSHHost struct to track config file origins
• Implement FindHostInAllConfigs() to locate hosts across all config files
• Fix "host not found" errors when editing/deleting hosts from included files
• Add GetAllConfigFiles() and GetAllConfigFilesFromBase() for config discovery
• Create UpdateSSHHostV2() and DeleteSSHHostV2() for cross-file operations
• Display config file source in edit and info forms for better visibility
• Add intelligent file selector for host addition when multiple configs exist
• Support -c parameter context with proper file resolution
• Exclude .backup files from Include directive processing
• Maintain backward compatibility with existing SSH config workflows

Resolves limitation where hosts from included config files could be viewed
but not edited, deleted, or properly managed through the interface.

+### Backup Configuration
+
+SSHM automatically creates backups of your SSH configuration files before making any changes to ensure your configurations are safe.
+
+**Backup Location:**
+- **Unix/Linux/macOS**: `~/.config/sshm/backups/` (or `$XDG_CONFIG_HOME/sshm/backups/` if set)
+- **Windows**: `%APPDATA%\sshm\backups\` (fallback: `%USERPROFILE%\.config\sshm\backups\`)
+
+**Key Features:**
+- Automatic backup before any modification
+- One backup per file (overwrites previous backup)
+- Stored separately to avoid SSH Include conflicts
+- Easy manual recovery if needed
+
+**Quick Recovery:**
+```bash
+# Unix/Linux/macOS
+cp ~/.config/sshm/backups/config.backup ~/.ssh/config
+
+# Windows
+copy "%APPDATA%\sshm\backups\config.backup" "%USERPROFILE%\.ssh\config"
+```
+
 ### Configuration File Options
 
 By default, SSHM uses the standard SSH configuration file at `~/.ssh/config`. You can specify a different configuration file using the `-c` flag:

 SSHM works directly with your standard SSH configuration file (`~/.ssh/config`). It adds special comment tags for enhanced functionality while maintaining full compatibility with standard SSH tools.
 
+### SSH Include Support
+
+SSHM fully supports SSH Include directives, allowing you to organize your SSH configurations across multiple files. This is particularly useful for managing large numbers of hosts or organizing configurations by environment, project, or team.
+
+**Include Examples:**
+```ssh
+# Main ~/.ssh/config file
+Host personal-server
+    HostName personal.example.com
+    User myuser
+
+# Include work-related configurations
+Include work-servers.conf
+
+# Include all configurations from a directory
+Include projects/*
+
+# Include with relative paths
+Include ~/.ssh/configs/production.conf
+```
+
+**Organization Examples:**
+
+*work-servers.conf:*
+```ssh
+# Tags: work, production
+Host prod-web-01
+    HostName 10.0.1.10
+    User deploy
+    ProxyJump bastion.company.com
+
+# Tags: work, staging  
+Host staging-api
+    HostName staging-api.company.com
+    User developer
+```
+
+*projects/client-alpha.conf:*
+```ssh
+# Tags: client, development
+Host client-alpha-dev
+    HostName dev.client-alpha.com
+    User admin
+    Port 2222
