[Infra] Remove dead EC2 Terraform module

[YHQZ1]

infra/modules/ec2/ exists but Hatch deploys containers on ECS Fargate, not EC2 instances. This module is unused and misleading for contributors reading the infra code.
Steps:

Verify infra/modules/ec2/ is not referenced in any .tf file: grep -r "ec2" infra/envs/
Delete infra/modules/ec2/
Run terraform plan in infra/envs/dev/ to confirm no breakage

[Infra] Remove Dead EC2 Terraform Module

1. Objective

Remove the deprecated, dead EC2 Terraform module and all associated code from the infrastructure repository to minimize code debt, clean up our state files, and eliminate maintenance overhead.

---

2. Affected Components & Files

• Module Directory: modules/ec2/
• Root Configurations: References across environment root directories (e.g., environments/dev/main.tf, environments/prod/main.tf)
• Variables & Outputs: Extraneous variables or output mappings no longer needed after module extraction.

---

3. Step-by-Step Implementation Plan

Step 1: State Inspection & Backup

Before altering any configurations, back up the remote state file to safeguard current cloud asset mapping against tracking data corruption.

Backup current state locally

• terraform state pull > state_backup_before_removal.json

List all resources currently tracked under the module

• terraform state list | grep "module.ec2"

Step 2: Clear Module Tracking from State File

To ensure Terraform stops tracking the deprecated infrastructure layer without trying to trigger an active AWS destruction cycle during deployments, safely purge it from the state ledger.

safely remove the module

• terraform state rm module.ec2

Step 3: Infrastructure Verification

Execute a dry-run plan across all active environments to guarantee that no unexpected resource modifications or accidental destruction side-effects occur.

ensure it safe

• terraform plan

---

4. Implementation Checklist / Next Steps

• Step 1: Pull state backup (terraform state pull > backup.json).

• Step 2: Clear module tracking from the state file (terraform state rm module.ec2).

• Step 3: Completely delete the modules/ec2/ directory and dangling variables from the code tree.

• Step 4: Run terraform plan to verify a clean exit state: "No changes. Your infrastructure matches the configuration."

• Confirm that CI/CD workflow linting and automated syntax validations pass successfully.
