Reviewer's guide (collapsed on small PRs)

Reviewer's Guide

This PR refactors the Docker integration to make the 'aiodocker' package an optional 'containers' extra by moving it out of core dependencies, adding a guarded import with a descriptive error, and updating test and type-check configurations.

Class diagram for updated container_service.py dependency handling

classDiagram
    class ContainerService {
        +run_container()
    }
    ContainerService : <<uses>> aiodocker (optional)
    note for ContainerService "aiodocker is now imported inside run_container() with ImportError handling"

File-Level Changes

Change	Details	Files
Guarded import for aiodocker with user-friendly error	Wrap import aiodocker in try/except Raise ImportError with install suggestion when missing	src/meltano/core/container/container_service.py
Moved aiodocker from core to optional 'containers' extra	Removed aiodocker from main dependencies Added a new 'containers' extras group including aiodocker	pyproject.toml
Include 'containers' extra in test and type-check sessions	Added 'containers' to pytest extras list Added '--extra=containers' in mypy invocation	noxfile.py
Updated lock file to reflect dependency changes	Regenerated uv.lock after dependency modifications	uv.lock

Assessment against linked issues

Issue	Objective	Addressed	Explanation
#8713	Remove aiodocker from the default/core dependencies so it is not installed by default.	✅
#8713	Make aiodocker available as an optional dependency via an extra (e.g., meltano[containers]).	✅
#8713	Update code to handle missing aiodocker dependency gracefully, providing a clear error message and instructions for installation.	✅
