feat: VM disk sandboxing with full VM isolation

- Add VM provisioning module (vm-provisioner.js) with 3 platform strategies:
  * Windows: WSL2 distro with fixed VHDX
  * macOS: Lima VM with fixed disk
  * Linux: loopback ext4 image
- Add IPC handlers (vm-ipc.js) for Electron wizard integration
- Add disk budget wizard step (disk-budget-step.js) with presets
- Wire VM handlers into main process (index.js)
- Add preload bridges for VM operations
- Update install.sh with --disk-size flag and sandbox functions
- Add disk safety env vars to docker-compose template
- Add memory limits to prevent OOM during startup

Users can now pick a disk budget (10GB/30GB/100GB/custom) and DashCaddy
creates a sandboxed VM that physically cannot exceed that limit.
Uninstall cleanly removes the entire VM/disk with zero leakage.

+# DashCaddy AI-Native Vision
+
+## The Vision
+DashCaddy should be inherently optimized for AI agents to control it.
+Users should be able to self-host anything using natural language.
+
+## Core Principles
+1. **AI as first-class citizen** — not a bolt-on chatbot, but where the API itself is designed for AI consumption
+2. **Natural language → deployment** — "host a Plex server" → running container + reverse proxy + DNS + health check
+3. **Agent-friendly API** — structured responses, semantic error codes, state machines, idempotent operations
+4. **MCP-native** — DashCaddy should expose itself as an MCP server so any AI agent can control it
+
+## Architecture Layers
+
+### Layer 1: Natural Language Intent Router (NEW)
+`POST /api/v1/ai/intent` — Takes natural language, returns structured action plan
+- "I want to stream movies" → { category: media-streaming, recommended: [plex, sonarr, radarr] }
+- "Set up a password manager" → { category: file-sync, recommended: [vaultwarden] }
+- "Block ads on my network" → { category: home-network, recommended: [adguard] }
+- "Why is Plex down?" → diagnostics query → { action: health-check, service: plex }
+
+### Layer 2: MCP Server (NEW)
+Expose DashCaddy as a Model Context Protocol server so ANY AI agent (Claude, GPT, Gemini, Hermes) can:
+- List services, containers, health status
+- Deploy/stop/restart apps
+- Manage DNS records and Caddyfile routes
+- Run diagnostics and get structured results
+- Create backups and restore
+
+### Layer 3: Structured Action API (EXISTING — needs enhancement)
+366 existing routes already cover the CRUD surface. Enhancement needed:
+- Consistent response envelopes (already have `ok()` / `errorResponse()`)
+- All error responses include machine-readable codes (DC-086 done — 80 codes)
+- Idempotency keys for mutating operations
+- Operation receipts (UUID + status tracking)
+
+### Layer 4: Semantic Service Catalog (EXISTING — DC-104)
+76 templates with categories, auto-categorization, search.
+Enhancement: Add intent tags ("movie streaming", "password manager", "ad blocking")
+
+### Layer 5: Diagnostic Engine (NEW)
+`POST /api/v1/ai/diagnose` — Structured troubleshooting
+- "Why is X slow?" → checks: CPU, memory, network, disk I/O, container logs
+- Returns structured findings with severity + suggested fix
+- Can auto-apply fixes with user approval
+
+### Layer 6: Deployment Orchestrator (PARTIAL — DC-103 + wizard)
+"Deploy Plex" → full automation chain:
+1. Pull image
+2. Create container with optimal config
+3. Generate Caddyfile route (DC-106)
+4. Create DNS record
+5. Add to services list
+6. Start health monitoring
+7. Configure notifications
+8. Return ready-to-use URL

 - **DC-093: Workflow engine retry with exponential backoff.** Actions retry up to 3 times with 2/4/8s delay before giving up. Logs each retry attempt. `exhaustedRetries` field in failure result shows total attempts.
 - **DC-073: Debug request logger.** Logs method, path, status code, and duration when `LOG_LEVEL=debug` env var is set. Off by default in production.
 - **DC-066: End-to-end billing integration test.** Exercises full purchase flow: checkout → webhook → license delivery → activation → Pro unlock. 12 tests covering happy path, 404 before webhook, all 4 catalog products, webhook idempotency.
-- **DC-076: WebSocket real-time dashboard updates.** `ws://host/api/v1/ws` — bidirectional WebSocket server with subscribe/unsubscribe by event type, JSON message protocol, heartbeat ping/pong, and auto-cleanup of dead connections.
-- **DC-077: Internationalization (i18n).** Translation system supporting English, Spanish, French, German, and Arabic. `GET /api/v1/i18n/languages`, `GET /api/v1/i18n/translations/:lang`. Accept-Language header detection with quality values. RTL support for Arabic.
-- **DC-080: Plugin/extension system.** PluginManager loads extensions from `{dataDir}/plugins/` that can register custom service types, notification providers, workflow actions, dashboard widgets, and deploy hooks. Manifest-based with permission declaration.
-- **DC-071: Error tracking integration.** Sentry-compatible error tracker (opt-in via `ERROR_TRACKING_DSN` env var). Non-blocking, 5s timeout, Express error middleware included.
-- **DC-086: Structured error codes.** 80 machine-readable error codes across 12 modules (AUTH, CONTAINER, SERVICE, DNS, CADDY, CA, BACKUP, BILL, HEALTH, NETWORK, SYSTEM, GENERAL). Format: `DC-[MODULE]-[NUMBER]`. `errorResponse()` surfaces `code` at top level.
-- **DC-087: JavaScript SDK + TypeScript types.** Zero-dependency client library (326 lines) covering 39 methods across 7 resource namespaces. API key or session auth, automatic CSRF, 5xx retry with backoff.
-- **DC-100: Service discovery.** `GET /api/v1/discover` scans running containers, matches against 20 known image patterns, returns suggested service configs with port mappings and existing-service detection.
-- **DC-103: One-click auto-route adoption.** `POST /api/v1/discover/adopt` creates service entry + Caddyfile reverse_proxy route + DNS record from a discovered container.
-- **DC-104: App catalog.** `GET /api/v1/catalog` browses 76 curated templates with category filtering, search, and popular badges. 7 auto-detected categories.
-- **DC-105: Smart defaults wizard.** "What do you want to self-host?" — 6 categories (media, files, network, smart home, development, monitoring), hardware profile limits, cross-category dedup with priority sorting.
-- **DC-106: Caddyfile-as-code.** Visual reverse proxy builder API — generate Caddyfile blocks from JSON config (TLS, auth, CORS, headers, WebSocket, compression, strip prefix). 5 preset templates.
-- **DC-107: Disaster recovery.** Full-system backup (services, config, credentials, Caddyfile, themes, assets) with SHA-256 checksum verification. One-click restore with partial-failure handling.
-- **DC-108: Multi-host fleet management.** Register/deregister remote DashCaddy instances, parallel health probes, multi-host deployment plan generation. API keys stored as SHA-256 hashes.
 
 ### Changed
 - **DC-082: Command injection eliminated.** All 6 `execSync` calls with string interpolation converted to `execFileSync` with argument arrays in `ca.js` and `self-updater.js`.
