feat: context-aware completions with dynamic resource names

- Hide attach-server/detach-server from --help (only relevant with --project)
- --project shows only project-scoped commands in tab completion
- Tab after resource type fetches live resource names from API
- --project value auto-completes from existing project names
- Stop offering resource types after one is already selected
