feat: Add complete stack.toml files with full metadata

Each stack.toml now includes:
- [stack] section: name, description, version, category, author
- [compose] section: file reference
- [variables] section: secrets where required
- [ports] section: internal port mappings
- [volumes] section: volume definitions
- [healthcheck] section: health check configuration

Stacks updated:
- prometheus
- grafana
- gotify
- vaultwarden
- node-exporter
