feat: add Docker watch mode for dynamic container sessions
- Add --docker-watch CLI flag to watch for containers with webterm-command label - Containers with label 'auto' get bash exec, otherwise use label as command - Dynamic dashboard updates via SSE when containers start/stop - Add /tiles endpoint for JSON tile list - Multi-stage Dockerfile for minimal production image - Update README with docker-watch documentation The docker watcher monitors Docker events and automatically: - Adds terminal tiles when labeled containers start - Removes tiles when containers stop - Notifies dashboard via SSE for live updates
