Enhancement: docker plugin

I've built for fun and for my own use a docker plugin.
If you think it could interest other users, I'd be happy to work with you to have it packaged in your repo.
You can find it here for now : https://github.com/Wayrkin/tmux-dracula-docker

It has :
- stats for running containers, memory usage and disk space
- compose state in working dir (up/down/partial)
- caching for "heavy" stats
- dracula-type customisation

It is missing, for now :
- fg/bg customisation (`@dracula-docker-colors`)
- compatibility with docker-compose v1 (`docker-compose` instead of `docker compose`)

I'm of course open to critics and suggestions.
disclaimer : it is fully built with AI (Claude Sonnet 5) but with my directives and guiding all along

Start by reviewing the proposed plugin at https://github.com/Wayrkin/tmux-dracula-docker and comparing it with the tmux repository's existing plugin structure. Done requires an agreed packaging approach, including the listed Docker Compose compatibility and color customization gaps.
