Bug Fixes

Fix Proxmox auto-register/auth failures by aligning the v5 agent and server auth path during setup and registration. (#1303)
Fix Proxmox cluster endpoint selection, per-node TLS endpoint reuse, and VM memory fallback so clustered nodes and guests report correctly. (#1319)
Fix host-agent temperature linking for Proxmox nodes so node temperatures prefer the linked agent path instead of falling back to SSH unnecessarily. (#1319)
Fix Ceph monitor and manager counts when ceph status only exposes count fields or richer servicemap data. (#1319)
Fix FreeBSD disk SMART temperature collection by retrying smartctl with the right device types for ada*, da*, and nvd* disks. (#1254)
Fix QNAP upgrades leaving duplicate agent/watchdog processes behind after install. (#1317)
Fix custom OpenAI-compatible endpoints hiding non-OpenAI model IDs from the model picker. (#1320)

Runtime Hardening

Lock the v5 runtime to single-tenant behavior so dormant multi-tenant code paths are bypassed instead of half-working.
