Optimize test suite with testing.Short() guards

- Add Short() guards to slow CLI tests (2-4s each)
- Add Short() guards to slow API/integration tests (3-11s)
- Add Short() guard to hanging daemon discovery test (29s timeout)
- Short test suite now runs in ~6s (down from 5+ minutes)

Run 'go test -short ./...' for fast iteration
Run 'go test ./...' for full coverage
