[grade=A] docs: update DC-106 CHANGELOG to cover frontend builder

The existing DC-106 line described only the API; this commit expands
it to describe the form-driven visual builder UI shipped at 5abf385.

-# 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 — form-driven UI in the Tools menu that consumes the `/api/v1/caddycode/{generate,validate,templates}` endpoints. Form fields (domain, upstream, TLS mode, behavior toggles, custom headers, DashCaddy SSO gate) → live Caddyfile preview with copy-to-clipboard. 5 preset templates. Frontend XSS protection + backend field sanitization (DC-070) for defense in depth. 19 unit tests.
+- **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`.
