Add working service file tracking system

- Safely copied actual working service files from system
- Created systemd-symlinks directory to track deployed versions
- Found key differences: service name is apt-ostree.service (not apt-ostreed.service)
- Service uses Type=dbus with direct D-Bus integration
- Updated .gitignore to track symlinks for version control
- Added sync-service-files.sh script for future deployments
- Ensures project reflects current reality of deployed files

+# Systemd and D-Bus Service File Tracking
+
+This directory contains symlinks to the actual service files that are currently installed and working in the system.
+
+## Purpose
+- Track the current reality of what's deployed and working
+- Ensure project files match what's actually being used
+- Allow git to track changes to the working service files
+
+## Files to Track
+- `/etc/systemd/system/apt-ostree.service` - Systemd service file (actual working version)
+- `/usr/share/dbus-1/system-services/org.debian.aptostree1.service` - D-Bus activation service (actual working version)
+- `/etc/dbus-1/system.d/org.debian.aptostree1.conf` - D-Bus policy file (actual working version)
+
+## Key Differences Found
+- **Service Name**: Actual service is `apt-ostree.service` (not `apt-ostreed.service`)
+- **Service Type**: Uses `Type=dbus` (not `Type=simple`)
+- **D-Bus Integration**: Direct D-Bus integration with `BusName=org.debian.aptostree1`
+- **Security**: More restrictive security settings than our project version
+
+## Usage
+After making changes to the service files in the system, copy them here to track changes in git.
