Add Docker Compose support

[alexandreroman]

Summary

• Add references/core/docker-compose.md covering how to run Temporal with Docker Compose (and Podman Compose)
• Includes minimal compose file, worker integration, healthcheck best practices, and tips for development
• Update SKILL.md description to trigger on Docker/container-related queries
• Add cross-reference from dev-management.md to the new Docker Compose guide

Details

This adds a new reference document for running a Temporal dev environment using Docker Compose as an alternative to temporal server start-dev. It covers:

• Minimal compose.yaml with healthcheck
• Connecting workers (as containers or from host)
• Podman Compose compatibility
• Key ports and configuration tips

Test plan

• Verify the skill triggers on Docker Compose-related queries (e.g. "add Temporal to Docker Compose")
• Review references/core/docker-compose.md for accuracy
• Confirm cross-references from SKILL.md and dev-management.md are correct
