k3s host prep:
- Add iSCSI initiator install+enable (Fedora: iscsi-initiator-utils,
Ubuntu: open-iscsi) — required by Longhorn
- Add Longhorn disk label to k3s server+agent configs
- Add Longhorn disk annotation operation in post-install hardening
CLI:
- Add `labctl provision asahi` command with interactive install guide
- Change default SSH user from "michal" to "lab" in all commands
- Change admin user in bastion progress callback to "lab"
Asahi provisioning fixes:
- Download installer_data.json locally (installer reads it as file)
- Use REPO_BASE to serve upstream ZIP from bastion (LAN speed)
- Fix ZIP32 vs ZIP64: serve original upstream ZIP unmodified
(our repackaged ZIP used ZIP64 which breaks Asahi urlcache)
- Add /data/asahi-repo fallback path for k3s container PVC mount
- Deploy script syncs asahi-repo to bastion pod after deployment
