Changelog

[Unreleased]

Integration Testing Suite: Complete integration testing infrastructure
- comprehensive_integration_test.py - Full test suite with 24 tests across 7 categories
- run_integration_tests.sh - Test runner with proper setup and error handling
- quick_test.py - Quick validation script for basic functionality
- Support for verbose output, JSON output, and specific test categories
- 100% SUCCESS RATE ACHIEVED - All 24 integration tests passing <<<<<<< HEAD =======
Modularized all CLI commands into separate modules under client/commands/.
Each command module now exports setup_parser and run functions for consistency.
Comprehensive test script for client CLI refactor.

D-Bus Method Registration: Added missing methods to AptOstreeSysrootInterface
- GetDeployments() - Returns deployments as JSON string
- GetBootedDeployment() - Returns currently booted deployment
- GetDefaultDeployment() - Returns default deployment
- GetActiveTransaction() - Returns active transaction details
Systemd Service Hanging: Fixed daemon signal handling and restart behavior
- Changed from await asyncio.Event().wait() to while self.running: await asyncio.sleep(1)
- Added proper timeouts and kill modes to systemd service
- Service now restarts cleanly in ~2 seconds
apt-layer.sh Integration: Fixed daemon path detection
- Created symlink from /usr/local/bin/apt-ostree to actual daemon
- All apt-layer.sh daemon commands now working correctly
D-Bus Auto-Activation: Created proper D-Bus service file
- org.debian.aptostree1.service - Enables auto-activation when D-Bus methods called
- Fixed environment setup issues causing Spawn.FailedToSetup errors
- Daemon now auto-starts correctly via D-Bus activation
