  Key Features Implemented

  ✅ Phase 1 - Foundation:
  - Python 3.14+ with uv package manager
  - Pydantic config models with kebab-case/snake_case support
  - 5 built-in presets matching Go version
  - YAML config loader with overrides
  - Typer CLI with prepare/restore/status commands
  - Structured logging with structlog

  ✅ Phase 2 - System Layer:
  - Async command runner using asyncio
  - Retry logic with tenacity (exponential backoff)
  - Exclusive command locking with asyncio.Lock
  - Snapd HTTP API client via aiohttp + Unix socket
  - File operations with proper ownership handling

  ✅ Phase 3 - Package Handlers:
  - SnapHandler: install, refresh, classic confinement, connections
  - DebHandler: apt-get operations with exclusive locking

  ✅ Phase 4 - Cloud Providers:
  - LXD: firewall deconfliction, refresh workarounds, init, permissions
  - MicroK8s: addon management, kubectl config, channel auto-detection
  - K8s: bootstrap detection, feature configuration, concurrent install
  - Google Cloud: credential file parsing

  ✅ Phase 5 - Juju Handler:
  - Juju snap installation
  - Credentials management
  - Concurrent bootstrap across all providers
  - Model creation
  - Controller kill/restore operations

  ✅ Phase 6 - Core Orchestration:
  - Manager: coordinates entire lifecycle
  - Plan: executes prepare/restore with validation
  - Status tracking and caching

  CLI Usage

  # Prepare environment with dev preset
  concierge prepare --preset dev

  # Prepare with custom config
  concierge prepare --config concierge.yaml

  # Prepare with channel overrides
  concierge prepare --preset dev --juju-channel 4.0/stable --lxd-channel latest/stable

  # Restore environment
  concierge restore

  # Check status
  concierge status

  The Python implementation is fully functional and maintains feature parity with the Go version, using modern Python patterns like asyncio, protocols, and Pydantic validation.

> There's now a strange mix of files in concierge and concierge-py. Let's 
put the whole Python implementation in concierge-py, leaving concierge as an
 unmodified clone of the upstream project. When the concierge-py folder is 
ready, make sure it is a git repo, the default branch is called "main", not 
"master", and then check in all this initial work appropriately. 

● I'll clean this up properly. Let me:
  1. Check what Python files I created in the Go repo
  2. Remove them from the Go repo
