Call stop_spinner in cleanup() to ensure any active spinner is stopped on exit. Consolidate duplicated qm set branches in ubuntu2604-vm.sh into a single invocation to reduce code duplication and simplify VM disk/serial configuration. Remove the explicit ide2 cloudinit device and redundant cloud-init status messages; setup_cloud_init() is still invoked when USE_CLOUD_INIT is enabled, keeping cloud-init configuration centralized.
Introduce optional Cloud-Init integration and better machine type handling for VMs. Changes include: loading cloud-init helpers lazily (load_cloud_init_functions), interactive cloud-init prompt/configuration (vm_prompt_cloud_init) and SSH key handling, a cloud icon for UI, and vm_machine_type_label for readable machine type display. Default machine type switched to q35 and displays the label in prompts and summaries. VM creation logic now conditionally attaches the cloudinit drive (ide2) and runs setup_cloud_init when enabled; otherwise it creates the VM without the cloudinit device. Post-install messaging now either shows cloud-init details or a guidance message about manual guest filesystem expansion. Minor UI/output adjustments and defaults updated accordingly.
Introduce a shared vm-core loader and refactor the Ubuntu 26.04 VM script to use reusable helper functions. misc/vm-core.func: add COMMUNITY_SCRIPTS_URL default and load_api_functions to dynamically source API helpers, then call load_api_functions from load_functions. vm/ubuntu2604-vm.sh: switch to sourcing the shared vm-core via COMMUNITY_SCRIPTS_URL, replace many inline UI and utility functions with generic vm_* helpers (vm_confirm_new_vm, vm_prompt_*, vm_select_storage, vm_define_disk_references, set_description, etc.), modernize quoting and pushd usage, simplify disk import/resizing logic, and set START_VM default to yes. Also update repository URLs to ProxmoxVED and adjust some behavior (machine type handling, storage/disk references). Overall this centralizes common functionality, reduces duplication, and prepares scripts to use the shared core utilities.
