New skill structure:
- src/skills/saga/SKILL.md — full agent with Product Brief + Trigger Map
- src/skills/freya/SKILL.md — full agent with UX Scenarios + UX Design
- bmad-manifest.json for each with capability menus
- references/ with all agent guides copied into skill directories
Skills are self-contained — no SKILL.md → workflow.md routing.
Follows BMad skill format: 2-part description, activation modes,
progressive disclosure, references loaded on demand.
Old activation files (saga.activation.md, freya.activation.md) kept
for now — can be removed after installer is updated.
