Introduces misc/build refactor_menu.func with comprehensive build and configuration functions for LXC containers in Proxmox VE. Refactors and modularizes initialization, storage selection, resource management, and advanced interactive configuration logic from misc/build.func.
Updated feature flag normalization to support both yes/no and 0/1 formats for ENABLE_NESTING, ENABLE_KEYCTL, and ENABLE_MKNOD. ENABLE_FUSE remains as yes/no for backward compatibility.
Commented out sections related to advanced feature flags, array-based FEATURES and PCT_OPTIONS, and dev mode exports that were causing compatibility and autologin issues. Added notes and TODOs for future integration, and moved MOTD/SSH setup for debugging to only run when containers are kept for troubleshooting.
Changed PCT_OPTIONS from an array to a string for proper export and compatibility with Proxmox pct. Features are now passed as a comma-separated string. Also updated install.func to use a literal heredoc for systemd override configuration.
Cleaned up dev mode and persistent log directory logic from build.func and install.func. Network connectivity status messages are now more direct, and unnecessary exports and re-parsing of dev_mode have been removed for clarity and maintainability.
Switches device configuration to use pct set format for GPU passthrough, simplifying config and improving GUI visibility. Updates GID handling logic for devices, streamlines fix_gpu_gids function, and improves container creation logging and API reporting. Removes commented-out MOTD/SSH debug setup from build copy.func.
Added new 'build copy.func' script for LXC container build and configuration in Proxmox VE, including variable initialization, storage management, resource allocation, and advanced interactive configuration. Updated 'build.func' to support new features and improved logic for container setup, storage selection, and app-specific defaults management.
Added quotes around build_log_copied and install_log_copied variables in conditional checks to prevent potential issues with unbound or empty variables during log display.
