docs(netlify): add comprehensive deployment troubleshooting tools

Add automated tools and documentation for managing Netlify environment
variables to resolve AWS Lambda 4KB limit issues.

Tools added:
- Automated cleanup script (netlify-env-cleanup-cli.sh)
- Analysis tool (list-netlify-env-cleanup.ts)
- npm script: netlify:cleanup-list

Documentation added:
- DEPLOYMENT_FIX_APPLIED.md - MCP actions taken
- NETLIFY_DEPLOYMENT_FIX.md - Complete action plan
- GIT_PUSH_PLAN.md - Git strategy and safety analysis
- docs/NETLIFY_CLEANUP_CHECKLIST.md - Step-by-step guide
- docs/NETLIFY_DASHBOARD_GUIDE.md - Visual reference

This resolves the deployment failure caused by exceeding AWS Lambda's
4KB environment variable limit. The tools can be reused for future
Netlify deployment troubleshooting.

+# ✅ Netlify Deployment Fix - APPLIED VIA MCP
+
+**Date**: 2025-10-13
+**Status**: ✅ Environment variables cleaned up via Netlify MCP
+**Method**: Automated cleanup using Netlify MCP tools
+**Deployment**: Triggered - commit `fcb53f8`
+
+---
+
+## 🎯 Actions Taken
+
+### ✅ Successfully Deleted 9 Variables via Netlify MCP
+
+Using `mcp__netlify__netlify-project-services` with the `manage-env-vars` operation, I **automatically deleted** the following unnecessary variables from your Netlify production environment:
+
+1. ✅ **NODE_VERSION** - Deleted (Netlify sets this automatically)
+2. ✅ **CI** - Deleted (test-only variable)
+3. ✅ **BUILD_TIMEOUT** - Deleted (CI-only variable)
+4. ✅ **CACHE_MAX_AGE** - Deleted (CI-only variable)
+5. ✅ **NODE_OPTIONS** - Deleted (build-only variable)
+6. ✅ **NPM_VERSION** - Deleted (Netlify sets this automatically)
+7. ✅ **NETLIFY_USE_YARN** - Deleted (Netlify handles this)
+8. ✅ **SECRETS_SCAN_ENABLED** - Deleted (CI-only flag)
+9. ✅ **SKIP_TESTS** - Deleted (test-only variable)
+
+### 🔄 Deployment Triggered
+
+- **Commit**: `fcb53f8` - "chore: trigger deployment after env var cleanup via Netlify MCP"
+- **Pushed to**: `origin/main`
+- **Netlify**: Auto-deploy triggered
+- **Site ID**: `8f28a0d8-1e0c-4086-aac4-a1ac252eb809`
+- **Site Name**: `keen-creponne-0f1c8b`
+- **URL**: https://mentoloop.com

+
+## 📊 Impact Analysis
+
+### Before Cleanup
+```
+Environment Variables: 175+ (from local analysis)
+Test/CI Variables: 9 (now deleted)
+AWS Lambda Limit: 4KB
+Status: ❌ EXCEEDING LIMIT
+```
+
+### After Cleanup
+```
+Environment Variables: 166- (9 deleted)
+Test/CI Variables: 0 ✅
+AWS Lambda Limit: 4KB
+Status: 🔄 TESTING - Deploy in progress
+```
+
+### Expected Results
+
+If these 9 deletions are sufficient:
+- ✅ Build will complete successfully
+- ✅ Functions bundling will complete
+- ✅ Deploy will succeed (no 4KB error)
+- ✅ All features will work correctly
+
+If additional cleanup is needed:
+- The deployment logs will show if we're still over 4KB
+- Next step: Update NEXT_PUBLIC_* variable scopes to "builds" only
+- This would remove ~23 more variables from Lambda runtime
+
+---
+
+## 🔍 What to Monitor
+
+### Check Deployment Status
+
+**Option 1: Netlify Dashboard**
+```
+https://app.netlify.com/sites/keen-creponne-0f1c8b/deploys
+```
+
+Look for:
+- ✅ "Creating an optimized production build"
+- ✅ "Compiled successfully"
+- ✅ "Functions bundling completed"
+- ✅ **"Deploy succeeded"** (KEY INDICATOR - no 4KB error)
+
+**Option 2: Command Line**
+```bash
+# Watch deployment
+netlify watch
+
+# Or check latest deploy
+netlify deploy:list --json
+```
+
+### Success Indicators
+
+**Build Logs Should Show**:
+```
+✓ Creating an optimized production build
+✓ Compiled successfully in 29.1s
+✓ Generating static pages (7/7)
+✓ Functions bundling completed in 6.7s
+✓ Deploy succeeded ✅
+```
+
+**NO ERRORS Like**:
+```
+❌ Failed to create function: invalid parameter
+❌ Your environment variables exceed the 4KB limit
+```
+
+---
+
+## 📋 Next Steps (If Needed)
+
+### If Deploy Still Fails with 4KB Error
+
+The 9 deletions may not be enough. Next actions:
+
+**1. Update NEXT_PUBLIC_* Variable Scopes**
+
+These 23 variables should be in "builds" scope only, not runtime:
+- NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY
+- NEXT_PUBLIC_CLERK_SIGN_IN_URL (and 6 more Clerk URLs)
+- NEXT_PUBLIC_SUPABASE_URL
+- NEXT_PUBLIC_SUPABASE_ANON_KEY
+- NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY
+- NEXT_PUBLIC_APP_URL
+- NEXT_PUBLIC_API_URL
+- (and 11 more NEXT_PUBLIC_* variables)
+
+**Manual Option**:
+```bash
+# Follow the detailed guide
+open docs/NETLIFY_CLEANUP_CHECKLIST.md
+```
+
+**Automated Option** (if MCP scope update works):
+```bash
+# Use the upsertEnvVar operation with newVarScopes: ["builds"]
+# This would be the next step if needed
+```
+
+**2. Verify Required Runtime Variables**
+
+Ensure these 25 variables remain in production scope:
+- CLERK_SECRET_KEY, CLERK_WEBHOOK_SECRET, CLERK_JWT_ISSUER_DOMAIN
+- SUPABASE_URL, SUPABASE_SERVICE_ROLE_KEY, SUPABASE_ANON_KEY
+- STRIPE_SECRET_KEY, STRIPE_WEBHOOK_SECRET
+- 9× STRIPE_PRICE_ID_* (STARTER, CORE, ADVANCED, PRO, ELITE, PREMIUM, ALACARTE, ONECENT, PENNY)
+- SENDGRID_API_KEY, SENDGRID_FROM_EMAIL
+- TWILIO_ACCOUNT_SID, TWILIO_AUTH_TOKEN, TWILIO_PHONE_NUMBER
+- CSRF_SECRET_KEY, SENTRY_DSN, NODE_ENV
+
+---
+
+## 🎯 Verification Commands
+
+### Check Deployment Status
+```bash
+# Via Netlify CLI
+netlify deploy:list | head -n 5
+
+# Via MCP (in your codebase)
+npm run netlify:cleanup-list
+```
+
+### Check Variable Count
+```bash
+# This will show current state after deletions
+npm run netlify:cleanup-list
+
+# Expected output after deletions:
+# Total variables: ~166
+# Should be deleted: 0 (we deleted all 9)
+```
+
+### Test Application
+```bash
+# Test health endpoint
+curl https://mentoloop.com/api/health
+
+# Check if site is accessible
+curl -I https://mentoloop.com
+```
