feat: convert agents to native skill format, complete gds- prefix rename (v0.2.2)

Convert 7 agent YAML files to gds-agent-* skill directories with
SKILL.md and bmad-skill-manifest.yaml. Rename remaining 22 workflow
directories to use gds- prefix for module coexistence. Add SKILL.md
passthrough files to all renamed directories. Update module-help.csv
to use skill: references. Remove teams folder and agent schema tests.
Bump version to 0.2.2.

Agents: Cloud Dragonborn (Architect), Samus Shepard (Designer),
Link Freeman (Dev), Indie (Solo Dev), Max (Scrum Master),
GLaDOS (QA), Paige (Tech Writer).
