install.sh --update not applying architecture migration properly

[ClaytonHunt]

Issue Description

The install.sh --update script is not properly applying the architecture migration for existing CARL installations.

Current Behavior

• User runs install.sh --update
• Script detects current version 1.4.5
• Architecture migration doesn't run properly
• Missing agent files and incorrect command structure persist

Expected Behavior

• All 11 specialist agent files should be installed in .claude/agents/
• Commands should be organized under .claude/commands/carl/ subdirectory
• All template files should have .carl extensions
• New specs folder should be created

Environment

• CARL Version: 1.4.5 (already latest)
• Platform: Linux (WSL2)
• Project: Existing CARL installation

Files That Were Missing/Incorrect

Missing Agent Files:

• carl-api-designer.md
• carl-devops-analyst.md
• carl-performance-analyst.md
• carl-quality-analyst.md
• carl-security-analyst.md
• carl-ux-designer.md

Command Structure:

• Commands were in .claude/commands/ instead of .claude/commands/carl/

Missing Folders:

• .carl/specs/ folder with format specifications

Workaround Applied

Manual file copying from reference repository resolved all issues.

Suggested Fix

The migration logic in install.sh may need review to ensure it properly handles cases where the version is already current but files are missing from previous incomplete migrations.
