Updated all internal references for the rename:
- CLAUDE.md: New purpose statement, updated structure, added manifesto info
- README.md: Updated title, clone URL, folder structure
- commands/retro.md: Changed flowmade-one/ai to flowmade-one/architecture
The actual Gitea rename should be done after merging this PR.
