# SECTION 2: PRE-FLIGHT CHECKS & SYSTEM VALIDATION
# ==============================================================================
#
# Runs comprehensive system checks BEFORE container creation to catch common
# issues early. This prevents users from going through the entire configuration
# menu only to have creation fail due to a system-level problem.
#
# Checks performed (via run_preflight):
# - Kernel: keyring limits (maxkeys/maxbytes for UID 100000)
# - Storage: rootdir support, vztmpl support, available space
# - Network: bridge availability, DNS resolution
# - Repos: enterprise repo subscription validation
# - Cluster: quorum status (if clustered)
# - Proxmox: LXC stack health, container ID availability
# - Template: download server reachability
#
# Design:
# - All checks run and results are collected (no exit on first failure)
# - Clear, actionable error messages with suggested fixes
# - Reports "aborted" status to telemetry (not "failed")
# - Uses existing exit codes for consistency with error_handler/api.func
