Validate Terraform

1#!/usr/bin/env bash
2# validate-terraform.sh
3# Runs the Terraform pre-deployment validation preflight sequence and prints a
4# compact PASS/FAIL/SKIP summary plus the captured error text for any failed step.
5#
6# The script runs every check even if an earlier one fails, so you get a complete
7# verdict in a single call. It never fixes anything - it only runs and reports, so
8# you can jump straight to remediation for any failed step.
9#
10# Steps: terraform present, az present, authenticated, init, fmt -check, validate,
11#        plan, state list, Go-style {{ .Env.* }} template-variable scan.
12#
13# Usage:
14#   ./validate-terraform.sh [infra-dir] [subscription-id]
