refactor(ci): decouple from upstream Parity infrastructure

Replace Parity-specific infrastructure dependencies with Pezkuwi's own:
- S3 release uploads → GitHub Releases (gh CLI)
- parity-zombienet runner labels → pezkuwi-runner
- Grafana/Loki log URLs → disabled (use GH artifacts)
- Matrix notifications → disabled (pending Pezkuwi Matrix)
- paritytech issue links → pezkuwi tracking issues
- paritytech Docker image refs → pezkuwi-sdk-frame in cmd.py
- Add mirror-ci-image.yml workflow for GHCR image mirroring
- Document upstream shared tools (resolc, try-runtime, evm-test-suite)
