feat: Implement comprehensive Debian packaging improvements and enhanced CI workflow

- Enhanced Package Information: Expanded PackageInfo struct with 23 fields including section, priority, maintainer, homepage, size, dependencies, and more - Real Package Data Extraction: Integrated dpkg and apt-cache for actual package information instead of mock data - Professional Debian Packaging: Added man pages, shell completions, postinst/prerm scripts, triggers, and lintian overrides - Enhanced Build System: Improved debian/rules with cross-compilation support, enhanced build.sh with options and validation - CI Workflow Updates: Added missing build dependencies, enhanced package validation, lintian quality checks, and comprehensive reporting - Quality Assurance: Added lintian validation, enhanced file checking, and professional packaging standards - Documentation: Comprehensive README.Debian with build instructions and troubleshooting guide Resolves mock package issues and provides production-ready Debian packaging infrastructure.

+apt-ostree for Debian
+====================
+
+This is the Debian packaging for apt-ostree, a tool for managing atomic,
+immutable deployments on Debian and Ubuntu systems using OSTree as the backend.
+
+Building the Package
+-------------------
+
+To build the Debian package:
+
+1. Install build dependencies:
+   ```bash
+   sudo apt-get install build-essential devscripts debhelper dh-cargo
+   sudo apt-get install libostree-dev libglib2.0-dev libcurl4-gnutls-dev
+   sudo apt-get install libssl-dev libsystemd-dev libmount-dev libselinux1-dev
+   sudo apt-get install libapt-pkg-dev
+   ```
+
+2. Install Rust toolchain:
+   ```bash
+   curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+   source ~/.cargo/env
+   ```
+
+3. Build the package:
+   ```bash
+   # Using the build script (recommended)
+   ./debian/build.sh
+   
+   # Or manually
+   dpkg-buildpackage -us -uc -b
+   ```
+
+4. Install the package:
+   ```bash
+   sudo dpkg -i ../apt-ostree_*.deb
+   sudo apt-get install -f  # Install any missing dependencies
+   ```
+
+Package Structure
+----------------
+
+The package installs the following components:
+
+- Binary: `/usr/bin/apt-ostree`
+- Man page: `/usr/share/man/man1/apt-ostree.1`
+- Bash completion: `/usr/share/bash-completion/completions/apt-ostree`
+- Zsh completion: `/usr/share/zsh/vendor-completions/_apt-ostree`
+- Configuration: `/etc/apt-ostree/config.toml`
+- Data directory: `/var/lib/apt-ostree`
+- Log directory: `/var/log/apt-ostree`
+
+Configuration
+------------
+
+After installation, apt-ostree will create a default configuration file at
+`/etc/apt-ostree/config.toml`. You can modify this file to customize the
+behavior of apt-ostree.
+
+Dependencies
+-----------
+
+apt-ostree requires the following system packages:
+
+- ostree (>= 2025.2)
+- systemd
+- libapt-pkg7.0 (>= 3.0.0)
+- libostree-1-1 (>= 2025.2)
+
+Development
+----------
+
+For development builds, you can use the local options:
+
+```bash
+# Enable debug mode
+export DH_VERBOSE=1
+export APT_OSTREE_LOG_LEVEL=debug
+
+# Build with debug symbols
+export CARGO_PROFILE_RELEASE_DEBUG=1
+
+# Build the package
+dpkg-buildpackage -us -uc -b
+```
+
+Troubleshooting
+--------------
+
+If you encounter build issues:
+
+1. Ensure all build dependencies are installed
+2. Check that Rust toolchain is properly configured
+3. Verify OSTree development libraries are available
+4. Check build logs in `debian/cargo/target/`
+
+For runtime issues:
+
+1. Check the configuration file at `/etc/apt-ostree/config.toml`
+2. Verify OSTree is properly configured on the system
+3. Check logs in `/var/log/apt-ostree/`
+4. Ensure proper permissions on OSTree directories
+
+Reporting Bugs
+-------------
+
+Please report bugs to the project issue tracker:
+https://github.com/robojerk/apt-ostree/issues
+
+Include the following information:
+- Debian/Ubuntu version
+- apt-ostree version
+- Error messages and logs
+- Steps to reproduce the issue
