feat!: migrate command namespace from speckit.* to adlc.*

- Change primary command names from speckit.* to adlc.*
- Add backward compatibility aliases (speckit.* and short forms)
- Update catalog.json with adlc.* command names
- Delete legacy setup-architecture.{sh,ps1} scripts
- Fix setup-architect.ps1 help text to reference correct script name

Breaking change: Extension commands now use adlc.* prefix as primary.
Backward compatibility maintained via aliases.
