Add dedicated Nexus One AI Workstation ISO build path
- New build-iso-workstation.sh / autoinstall/user-data-workstation: writes the workstation tier marker (/opt/cezen/tier), reuses the Server S (starter) hardware profile and Ansible playbook under the hood - firstboot-setup.sh: additive WORKSTATION_MODE branch (gated on CEZEN_TIER=workstation) skips the Server tier-selection menu entirely — Workstation is never offered as a Server S/M/L/Max choice. Non-workstation installs are unaffected. Also relabels the Server tier menu to Server S/M/L/Max, matching the earlier portal rename - install.sh and the Ansible playbooks are unchanged; only the pre/post marker files differ between a Server S and Workstation install - README.md + MIGRATION_NOTES.md updated with the new build path and what is still manual (CEZEN_TIER isn't yet templated into the deployed cezen-api systemd unit — tracked as follow-up)

# Nexus One AI — Workstation Autoinstall
|
||||
# Hardware target: personal AI appliance (Mini-ITX / SFF / DGX Spark class)
|
||||
# GPU: NVIDIA DGX Spark, RTX 5090 Workstation, or RTX PRO 6000
|
||||
# Workstation (1 GPU)
|
||||
# RAM: 64 GB DDR5
|
||||
# Storage: 1× 2 TB NVMe SSD (single drive — simple LVM)
|
||||
# Network: 2.5 GbE (single interface)
|
||||
# Users: 1-3 active, 5 max — not a shared server, no HA
|
||||
#
|
||||
# This reuses the same compact single-GPU install profile as the Server S
|
||||
# ("starter") image below — same hardware class, same Ansible playbook
|
||||
# (ansible/starter.yml) — but is a distinct, standalone product category
|
||||
# (Nexus One AI Workstation), not part of the Server S/M/L/Max ladder.
|
||||
# See cezen_license.WORKSTATION_TIER / TIER_MATRIX["workstation"].
