Download cv4pve-cli 2.3.0

Commands
- Added a task command tree to inspect and follow async Proxmox tasks by UPID: task list, task show, task wait, task log (with --follow to tail live, polling every 2s) and task stop.
- Every alias now honors --wait to block until the async Proxmox task finishes (previously the flag was ignored on aliases — start/backup/migrate were fire-and-forget).
Aliases
- Added do restore vm and do restore ct to restore a guest from a vzdump backup archive.
- Added Ceph read aliases: get ceph status/flags and get node ceph status/osds/mons/mgrs/pools/fs/config.
Scripting
- Commands now return semantic exit codes (0 ok, 1 generic, 2 auth/config, 3 not-found, 4 api/server, 5 task-failed, 6 validation) and print errors to stderr instead of stdout — previously failures printed to stdout and still returned 0.
Bug fixes
- Fixed a startup crash (ArgumentNullException) that made every command fail — the --log-level option was not registered.
Documentation
- Added docs/commands.md (core command reference) and docs/aliases.md (full alias list, regenerable via alias list --output markdown), linked from the README.
- Added tips for running cv4pve-cli inside AI coding assistants (docs/AI-AGENTS.md).
