CRITICAL: Fix install script to include normalization fixes

- LLMS: feature/dev-workflow-docs → review/llms-pr1-head
- This ensures users get CRITICAL normalization fixes (commit eb1424e)
- Without these fixes, GPT-5 API returns 400 errors on image/tool payloads
- CCR: remains on feature/dev-workflow-docs (has reasoning control: d64dc24)

Verified branches contain:
✅ LLMS eb1424e: normalizeImageContent() + normalizeToolMessages()
✅ CCR d64dc24: inline reasoning control tokens (:quick, :deep, etc)
✅ Both: Complete documentation and workflow enhancements

 # quickstart-gpt5.sh - One-command setup for CCR×GPT-5 integration
 # 
 # Purpose: Give contributors a reproducible setup to run the CCR×GPT-5 PR stack locally  
-#          Uses feature/dev-workflow-docs branches with ALL 6 PRs combined
+#          Uses review/llms-pr1-head (with CRITICAL normalization fixes) + feature/dev-workflow-docs
 #
 # Usage:
 #   export OPENAI_API_KEY=sk-...
 #   bash quickstart-gpt5.sh
 #
 # This script will:
-# 1. Clone/update both repos to feature/dev-workflow-docs (contains ALL 6 PRs)
-# 2. Build LLMS with complete GPT-5 integration (normalization + reasoning + docs)
-# 3. Link LLMS to CCR using yalc (following dev-workflow pattern)  
-# 4. Build CCR with complete enhancements (reasoning tokens + docs + workflows)
-# 5. Use existing CCR config.json with env-var interpolation
-# 6. Provide clear next steps for testing
+# 1. Clone LLMS to review/llms-pr1-head (CRITICAL: has normalization fixes)
+# 2. Clone CCR to feature/dev-workflow-docs (has workflow + docs enhancements)
+# 3. Build LLMS with GPT-5 normalization fixes that prevent 400 errors
+# 4. Link LLMS to CCR using yalc (following dev-workflow pattern)  
+# 5. Build CCR with reasoning control + documentation enhancements
+# 6. Use existing CCR config.json with env-var interpolation
