♻️ Run both maintain scans independently (;)

The maintain aggregator used &&, so if maintain:knip exited non-zero (e.g. an
unused export) maintain:outdated never ran and the report was partial. Switch
to ; so both scans always run and every finding surfaces. CI still treats the
job as non-blocking, so the trailing exit code is moot there. Zero new dep.
