* Interactive option to **remove all existing APT proxy configurations**, restoring default behavior for all selected targets.
* Support for **selective skipping** of LXC/VM IDs via comma-separated input.
* Prompt to **overwrite existing config** if `00aptproxy` already exists inside target.
* Interactive mode to **apply** or **remove** proxy across:
* LXC containers
* VMs with QEMU Guest Agent
* Proxmox host node
**Changed:**
* Refactored script for **simplified structure** with clearer flow and prompts.
* Improved compatibility check: now uses `/etc/os-release` for accurate distro detection (Ubuntu/Debian only).
* Replaced legacy check via `lsb_release` for faster and leaner execution.
**Fixed:**
* Old proxy files like `01proxy` are now reliably **detected and removed** before applying a new config.
* Ensured **port and proxy format** strictly follow APT specification:
`Acquire::http::Proxy "http://<host>:<port>";`
