docs: restructure walkthrough as multi-page presentation

Transform walkthrough into presentation-style format:
- Each page is a presentation slide
- Navigate with arrow keys or sidebar
- Can be used as speaker notes during presentations
- Also works as self-guided tutorial

Structure (10 pages + appendix):
1. The Problem - Current state, why redisctl exists
2. Enter redisctl - First CLI tool, key benefits
3. Installation & Setup - Get started, profiles
4. Raw API Layer - Direct REST access
5. Human-Friendly Layer - Better UX, type-safe
6. Workflows Layer - Multi-step orchestration
7. Advanced Features - JMESPath, support packages, streaming
8. Library Architecture - Platform vision, reusable components
9. Next Steps - Try it, get involved, roadmap
Appendix - rladmin comparison

Benefits:
- Presentation-friendly navigation (page by page)
- Each page is focused and concise
- Natural flow from problem to solution
- Works for both live presentations and self-study
- Links to deep-dive documentation

Duration: 20-25 minutes as presentation, 45-60 minutes hands-on

+# 1. The Problem
+
+**Before redisctl: How did we manage Redis deployments?**
+
+## Redis Cloud
+
+### What Exists
+- 🖱️ **Web UI** - Point and click (not scriptable)
+- 🏗️ **Terraform Provider** - Good for IaC, not ad-hoc operations
+- 🌐 **REST API** - Documented but no tooling around it
+
+### The Gap
+❌ No CLI for day-to-day operations  
+❌ No way to script common tasks  
+❌ Must use UI or write custom bash scripts
+
+## Redis Enterprise
+
+### What Exists
+- 🖥️ **rladmin** - Powerful but limited
+  - Must SSH to cluster nodes
+  - Text output (hard to parse)
+  - Not cross-platform (Linux only on nodes)
+  - Single cluster at a time
+- 🌐 **REST API** - Large (~100+ endpoints), poorly documented
+  - Manual JSON construction
+  - No official tooling
+
+### The Gap
+❌ No remote management CLI  
+❌ No automation-friendly tools  
+❌ No multi-cluster support
+
+## The Reality
+
+**What everyone actually does:**
+
+```bash
+# The "best practice" before redisctl
+curl -X POST https://api.redislabs.com/v1/subscriptions \
+  -H "x-api-key: $KEY" \
+  -H "x-api-secret-key: $SECRET" \
+  -H "Content-Type: application/json" \
+  -d '{"name":"prod","cloudProviders":[...]}'
+
+# Then poll for completion
+while true; do
+  STATUS=$(curl -s https://api.redislabs.com/v1/tasks/$TASK_ID | jq -r '.status')
+  if [ "$STATUS" = "completed" ]; then break; fi
+  echo "Still waiting..."
+  sleep 2
+done
+
+# Then create database...
+# Poll again...
+# Repeat for every operation...
+```
+
+## Problems with This Approach
+
+1. ❌ **No type safety** - Typos cause runtime failures
+2. ❌ **Manual JSON** - Error-prone, hard to maintain
+3. ❌ **Polling loops** - Fragile, need manual error handling
+4. ❌ **Credential exposure** - API keys in shell history
+5. ❌ **Not portable** - Requires bash, curl, jq
+6. ❌ **No progress feedback** - Silent failures
+7. ❌ **Everyone reinvents** - Same scripts written over and over
+
+## Who This Affects
+
+- **Support Engineers** → Manual UI clicking, can't script diagnostics
+- **DevOps Teams** → Can't automate without Terraform
+- **Customers** → Build fragile bash scripts or don't automate
+- **Everyone** → Wastes time on operations that should be simple
+
+## The Core Problem
+
+**Redis had ZERO command-line tools for Cloud or Enterprise management**
+
+---
+
+**Next →** [2. Enter redisctl](./02-solution.md) - The first CLI tool
+
+**Demo:** Run `examples/presentation/01-before-redisctl.sh` to see this in action

+# 2. Enter redisctl
+
+**The FIRST command-line tool for Redis Cloud and Enterprise**
+
+## What is redisctl?
+
+A unified CLI that eliminates fragile bash scripts with:
+
+✅ Type-safe API clients  
+✅ Automatic async operation handling  
+✅ Support package automation  
+✅ Profile management with secure keyring  
+✅ Structured output (JSON, YAML, Table)  
+✅ Library-first architecture
+
+## Before vs After
+
+### Before: 50 Lines of Bash
+
+```bash
+curl + jq + while loops + manual polling + text parsing
+```
+
+### After: One Command
+
+```bash
+redisctl cloud database create \
+  --subscription-id 12345 \
+  --data '{"name": "mydb", "memoryLimitInGb": 1}' \
+  --wait
+```
+
+## Key Benefits
+
+### For Support Engineers
+- ✅ Remote cluster management (no SSH)
+- ✅ Support package automation (10 min → 30 sec)
+- ✅ Scriptable diagnostics
+
+### For DevOps Teams
+- ✅ CI/CD integration (JSON output)
+- ✅ Multi-cluster management (profiles)
+- ✅ Automation-friendly
+
+### For Developers
+- ✅ Reusable libraries
+- ✅ Type-safe API clients
+- ✅ Build custom tools
+
+## Metrics
+
+- **50+ API handlers** (21 Cloud + 29 Enterprise)
+- **85%+ test coverage** (production quality)
+- **Cross-platform** (macOS, Linux, Windows)
+- **v0.6.5** released and actively maintained
+
+## The Impact
+
+**One command replaces 50 lines of fragile bash**
+
+```bash
+# Everything just works
+redisctl cloud subscription list
+redisctl enterprise database list -o table
+redisctl enterprise support-package cluster --upload
+```
