Replace the duplicate-host check with a live Proxmox query, drop deployedTargets

Browse Source 
variables.nix's deployedTargets was a manually-maintained list with no
enforcement keeping it in sync with reality -- it caused two separate
false refusals in a row (naming a VM as deployed well after it had been
destroyed, then matching a target against itself once the list was
"corrected"). Static files can't track whether a resource still actually
exists.

create-proxmox-resource.sh's duplicate-host guard now queries the
Proxmox node directly (qm/pct's own name/hostname config, matched
against --host) instead. Also fixes a gap in that live check: it
originally swallowed ssh failures and would have silently treated "can't
reach the node" the same as "checked, nothing there" -- it now refuses
instead of guessing when the node can't be reached.

deployedTargets is removed entirely from variables.nix since nothing
else in the repo consumed it once this script no longer does; README.md's
Hosts table remains the sole source of truth for "(real, deployed)"
status. CLAUDE.md and the script's own --help/comments updated to match.

The "(real, deployed)" targets above are also tracked machine-readably in
`variables.nix`'s `deployedTargets` — keep both in sync when a deployment
changes. `scripts/create-proxmox-resource.sh` reads that list to refuse
creating a same-identity duplicate of an already-deployed host by accident.
This table is the only place "(real, deployed)" status is tracked — there's
no separate machine-readable copy to keep in sync. `scripts/create-proxmox-resource.sh`
guards against creating a same-identity duplicate of an already-deployed host
by checking the Proxmox node itself (live `qm`/`pct` state) rather than any
file in this repo, since a static list can't track whether a resource still
actually exists.
Each buildtype's `hosts/<name>/host.nix` carries the per-machine identity
(hostname, hostId, per-machine secrets, `system.stateVersion`) that must stay
