Add type=agent and type=role to bead schema (gt-ikyo1, gt-gzp2y)

- Add TypeAgent and TypeRole to IssueType enum in types.go
- Update IsValid() to include new types
- Add UI styles with distinct colors (cyan for agent, green for role)
- Add RenderType cases for consistent display

This enables creating agent beads (identity) and role beads (behavior
definitions) as part of the agent-as-bead architecture.
