robojerk 97a9c40d7e docs: Add comprehensive documentation and update planning 
- Add docs/README.md with project overview and current status
- Add docs/architecture.md with detailed architecture documentation
- Add docs/development.md with development guide for contributors
- Update .notes/todo.md to reflect architecture fix completion
- Update .notes/plan.md with completed phases and next priorities

Architecture fixes (daemon and dbus), bubblewrap integration are now complete.
Ready for OCI integration phase.

# apt-ostree Architecture Fix
## Problem
apt-ostree was implemented with the wrong architecture - all commands were client-only, bypassing the daemon entirely. This is incorrect according to rpm-ostree's architecture.
## Solution
Converted to proper daemon-based architecture following rpm-ostree patterns:
### Before (WRONG):
```rust
// Client directly calls system methods
let system = AptOstreeSystem::new("debian/stable/x86_64").await?;
system.install_packages(&packages, yes).await?;
```
### After (CORRECT):
```rust
// Client calls daemon via D-Bus with fallback
let result = call_daemon_with_fallback(
|client| Box::pin(client.install_packages(packages.clone(), yes, dry_run)),
|| Box::pin(async {
// Fallback to client-only if daemon unavailable
let system = AptOstreeSystem::new("debian/stable/x86_64").await?;
system.install_packages(&packages, yes).await?;
Ok("Packages installed successfully".to_string())
})
).await?;
```
## Benefits
1. **Proper Architecture**: Follows rpm-ostree's daemon-client model
2. **Transaction Management**: Daemon handles atomic operations
3. **Security**: Privileged operations isolated in daemon
4. **Reliability**: Fallback to client-only if daemon unavailable
5. **Scalability**: Multiple clients can use daemon simultaneously
## Implementation
- Created `DaemonClient` for D-Bus communication
- Added `call_daemon_with_fallback` helper function
- Updated all commands to use daemon-based architecture
- Maintained backward compatibility with fallback mechanism
