admin a042316d6d feat(agent): scaffold + proxmox interaction layer (slice 1)
Stand up the felhom-agent project (module gitea.dooplex.hu/admin/felhom-agent,
binary felhom-agent) and the internal/proxmox package: the typed library every
other agent module calls to talk to Proxmox.

- API-first Client (hand-rolled REST over net/http, PVEAPIToken auth) with typed
  read ops (version/nodes/status/lxc/config/storage) and async mutating ops
  (restore/vzdump/snapshot/rollback/delete-snapshot/setconfig/start/stop), each
  returning a UPID. WaitTask polls task status until stopped and asserts
  exitstatus OK (authz can surface at task exec, not the POST — phase1-2 §1.3).
- Fenced Privileged (root-CLI) backend for the THREE proven exceptions only
  (keyctl pct create, USB mount/fstab, SMART/sensors); each cites why it can't be
  the API. Fence is structural (Client never shells out, Privileged never HTTPs)
  and asserted in routing_test.go.
- TLS: SHA-256 leaf-cert pinning or CA file; insecure mode explicit + off by
  default. No blanket verification disable.
- 403 -> privilege-named APIError; failed task -> privilege-named TaskError.
- JSON config + env overrides (token never logged); slog logging.
- cmd/felhom-agent --selftest (read-only health report) + gated --selftest=task
  (reversible snapshot/rollback/delete exercise of WaitTask). No daemon loop yet.
- Types grounded in the spike findings and exact JSON shapes captured live from
  demo-felhom (PVE 9.2.2). Unit tests use a mock transport + runner.
