chore: Address code review feedback

Addresses Claude Code Review feedback items:

1. Delete deprecated setup-vertex-ai.sh script
   - Script was replaced by Makefile automation
   - Prevents confusion and risk of modifying tracked files

2. Replace hardcoded sleeps with kubectl wait
   - Use 'kubectl wait --for=condition=ready' for pods
   - More reliable than fixed timeouts
   - Reduced final sleep from 2s to 1s

3. Update SECURITY_DEV_MODE.md to reflect allow-list implementation
   - Code uses allow-list (ambient-code, default, vteam-dev)
   - Documentation was describing old deny-list approach
   - Now accurately documents current security posture

4. Add ShellCheck directive for intentional set +e
   - Documents why we continue on errors (collect all test results)

5. Document sys.path.insert in wrapper.py
   - Explains why runner-shell path manipulation is necessary
   - Clarifies dependency on RunnerShell framework

All changes improve code quality, documentation accuracy, and reliability.

 ## Identified Risks
 
-### 🔴 **HIGH RISK: Weak Namespace Check**
+### 🟢 **MITIGATED: Allow-List Namespace Validation**
 
-**Current:** Only rejects if namespace contains "prod"
+**Current:** Uses allow-list of specific namespaces (ambient-code, default, vteam-dev)
 
-**Risk Scenarios:**
+**Protection:**
 ```bash
-# Would PASS (incorrectly enable dev mode):
-NAMESPACE=staging DISABLE_AUTH=true ENVIRONMENT=local  # ❌ Dangerous
-NAMESPACE=qa-env DISABLE_AUTH=true ENVIRONMENT=local   # ❌ Dangerous
-NAMESPACE=demo DISABLE_AUTH=true ENVIRONMENT=local     # ❌ Dangerous

+# Would PASS (correctly enable dev mode):
+NAMESPACE=ambient-code DISABLE_AUTH=true ENVIRONMENT=local  # ✅ Allowed
+NAMESPACE=default DISABLE_AUTH=true ENVIRONMENT=local       # ✅ Allowed
+NAMESPACE=vteam-dev DISABLE_AUTH=true ENVIRONMENT=local     # ✅ Allowed
 
 # Would FAIL (correctly reject):
-NAMESPACE=production DISABLE_AUTH=true ENVIRONMENT=local # ✅ Good
-NAMESPACE=prod-east DISABLE_AUTH=true ENVIRONMENT=local  # ✅ Good

 ```

 ### 🟡 **MEDIUM RISK: No Cluster Type Detection**
