Migrate from Forgejo to Gitea

- Replace fj CLI with tea CLI across all commands
- Create new gitea skill, remove forgejo skill
- Update all agents to use gitea skill
- Update commands to use skill-based approach (reference skills instead of embedding CLI commands)
- Update all documentation (README, ARCHITECTURE, VISION, writing guides)
- Swap git remotes: origin now points to git.flowmade.one (Gitea)
