feat: VM snapshots and reboot_host through the API

get_vm_snapshots, create_vm_snapshot, delete_vm_snapshot and
rollback_vm_snapshot for VMs and containers, so netOrk's snapshot view
works on Proxmox as it does on VMware. Proxmox lists the live state as a
pseudo-snapshot named "current"; it is never reported or addressable.
Containers have no RAM state, so include_memory is ignored for them.

reboot_host() restarts the node with POST /nodes/{node}/status
command=reboot instead of /sbin/reboot over SSH.

 ## [Unreleased]
 
+### Added
+- `HypervisorDriver` contract methods `start_vm`, `stop_vm`, `reboot_vm`,
+  `suspend_vm` and `get_vm_config`. They accept a VM's name or vmid, raise
+  `ValueError`/`RuntimeError` instead of returning a result dict, and wait
+  for the Proxmox task to finish. `power_vm` is unchanged.
+- Snapshot methods `get_vm_snapshots`, `create_vm_snapshot`,
+  `delete_vm_snapshot`, `rollback_vm_snapshot` for VMs and containers
+  (containers never save RAM state).
+- `reboot_host()` restarts the node through the API instead of SSH.
+
+### Changed
+- `get_vms()` reports `vmid` as a string (`"100"`), following
+  napalm-device-types 2.0. Ordering stays numeric.
+
 ## [0.1.0] - 2024-01-01

+"""`get_packages` and the source coordinate OSV matching needs.

+A Proxmox node is a Debian host, so its packages are matched against Debian
+advisories — and OSV states those ranges in *source* package versions. Reporting
+the source package without its version leaves a consumer holding two numbers on
+different axes: `libldb2` is `2:2.11.0+samba4.22.11+dfsg-…` while its source,
+samba, is `2:4.22.11+dfsg-…`, and comparing the first against a samba range is
+meaningless.
+
+Measured before this was fixed: on three Proxmox nodes, **every one** of their
+2 349 packages carried a source package and no source version — 802 of 802,
+774 of 774, 773 of 773 — while twenty non-Proxmox hosts had both. The format
