Remove Electron settings panel (breaking change)

- Remove electron/settings/ folder
- Remove config-manager.ts and settings-window.ts
- Remove Configuration menu from app menu
- Remove config-presets IPC handlers
- Update README.md
- Clean up electron.d.ts

Note: This is a breaking change - users will lose existing presets

-# Deploy on Cloudflare Workers
-
-This project can be deployed as a **Cloudflare Worker** using the **OpenNext adapter**, giving you:
-
-- Global edge deployment
-- Very low latency
-- Free `workers.dev` hosting
-- Full Next.js ISR support via R2 (optional)
-
-> **Important Windows Note:** OpenNext and Wrangler are **not fully reliable on native Windows**. Recommended options:
->
-> - Use **GitHub Codespaces** (works perfectly)
-> - OR use **WSL (Linux)**
->
-> Pure Windows builds may fail due to WASM file path issues.
-
----
-
-## Prerequisites
-
-1. A **Cloudflare account** (free tier works for basic deployment)
-2. **Node.js 18+**
-3. **Wrangler CLI** installed (dev dependency is fine):
-
-```bash
-npm install -D wrangler
-```
-
-4. Cloudflare login:
-
-```bash
-npx wrangler login
-```
-
-> **Note:** A payment method is only required if you want to enable R2 for ISR caching. Basic Workers deployment is free.
-
----
-
-## Step 1 — Install dependencies
-
-```bash
-npm install
-```
-
----
-
-## Step 2 — Configure environment variables
-
-Cloudflare uses a different file for local testing.
-
-### 1) Create `.dev.vars` (for Cloudflare local + deploy)
-
-```bash
-cp env.example .dev.vars
-```
-
-Fill in your API keys and configuration.
-
-### 2) Make sure `.env.local` also exists (for regular Next.js dev)
-
-```bash
-cp env.example .env.local
-```
-
-Fill in the same values there.
-
----
-
-## Step 3 — Choose your deployment type
-
-### Option A: Deploy WITHOUT R2 (Simple, Free)
-
-If you don't need ISR caching, you can deploy without R2:
-
-**1. Use simple `open-next.config.ts`:**
-
-```ts
-import { defineCloudflareConfig } from "@opennextjs/cloudflare/config"
-
-export default defineCloudflareConfig({})
-```
-
-**2. Use simple `wrangler.jsonc` (without r2_buckets):**
-
-```jsonc
-{
-  "$schema": "node_modules/wrangler/config-schema.json",
-  "main": ".open-next/worker.js",
-  "name": "next-ai-draw-io-worker",
-  "compatibility_date": "2025-12-08",
-  "compatibility_flags": ["nodejs_compat", "global_fetch_strictly_public"],
-  "assets": {
-    "directory": ".open-next/assets",
-    "binding": "ASSETS"
-  },
-  "services": [
-    {
-      "binding": "WORKER_SELF_REFERENCE",
-      "service": "next-ai-draw-io-worker"
-    }
-  ]
-}
-```
-
-Skip to **Step 4**.
-
----
-
-### Option B: Deploy WITH R2 (Full ISR Support)
-
-R2 enables **Incremental Static Regeneration (ISR)** caching. Requires a payment method on your Cloudflare account.
-
-**1. Create an R2 bucket** in the Cloudflare Dashboard:
-
-- Go to **Storage & Databases → R2**
-- Click **Create bucket**
-- Name it: `next-inc-cache`
-
-**2. Configure `open-next.config.ts`:**
-
-```ts
-import { defineCloudflareConfig } from "@opennextjs/cloudflare/config"
-import r2IncrementalCache from "@opennextjs/cloudflare/overrides/incremental-cache/r2-incremental-cache"
-
-export default defineCloudflareConfig({
-  incrementalCache: r2IncrementalCache,
-})
-```
-
-**3. Configure `wrangler.jsonc` (with R2):**
-
-```jsonc
-{
-  "$schema": "node_modules/wrangler/config-schema.json",
-  "main": ".open-next/worker.js",
-  "name": "next-ai-draw-io-worker",
-  "compatibility_date": "2025-12-08",
-  "compatibility_flags": ["nodejs_compat", "global_fetch_strictly_public"],
-  "assets": {
-    "directory": ".open-next/assets",
-    "binding": "ASSETS"
-  },
-  "r2_buckets": [
-    {
-      "binding": "NEXT_INC_CACHE_R2_BUCKET",
-      "bucket_name": "next-inc-cache"
-    }
-  ],
-  "services": [
-    {
-      "binding": "WORKER_SELF_REFERENCE",
-      "service": "next-ai-draw-io-worker"
-    }
-  ]
-}
-```
-
-> **Important:** The `bucket_name` must exactly match the name you created in the Cloudflare dashboard.
-
----
-
-## Step 4 — Register a workers.dev subdomain (first-time only)
-
-Before your first deployment, you need a workers.dev subdomain.
-
-**Option 1: Via Cloudflare Dashboard (Recommended)**
-
-Visit: https://dash.cloudflare.com → Workers & Pages → Overview → Set up a subdomain
-
-**Option 2: During deploy**
-
-When you run `npm run deploy`, Wrangler may prompt:
-
-```
-Would you like to register a workers.dev subdomain? (Y/n)
-```
-
-Type `Y` and choose a subdomain name.
-
-> **Note:** In CI/CD or non-interactive environments, the prompt won't appear. Register via the dashboard first.
-
----
-
-## Step 5 — Deploy to Cloudflare
-
-```bash
-npm run deploy
-```
-
-What the script does:
-
-- Builds the Next.js app
-- Converts it to a Cloudflare Worker via OpenNext
-- Uploads static assets
-- Publishes the Worker
-
-Your app will be available at:
-
-```
-https://<worker-name>.<your-subdomain>.workers.dev
-```
-
----
-
-## Common issues & fixes
-
-### `You need to register a workers.dev subdomain`
-
-**Cause:** No workers.dev subdomain registered for your account.
-
-**Fix:** Go to https://dash.cloudflare.com → Workers & Pages → Set up a subdomain.
-
----
-
-### `Please enable R2 through the Cloudflare Dashboard`
-
-**Cause:** R2 is configured in wrangler.jsonc but not enabled on your account.
-
-**Fix:** Either enable R2 (requires payment method) or use Option A (deploy without R2).
-
----
-
-### `No R2 binding "NEXT_INC_CACHE_R2_BUCKET" found`
-
-**Cause:** `r2_buckets` is missing from `wrangler.jsonc`.
-
-**Fix:** Add the `r2_buckets` section or switch to Option A (without R2).
-
----
-
-### `Can't set compatibility date in the future`
-
-**Cause:** `compatibility_date` in wrangler config is set to a future date.
-
-**Fix:** Change `compatibility_date` to today or an earlier date.
-
----
-
-### Windows error: `resvg.wasm?module` (ENOENT)
-
-**Cause:** Windows filenames cannot include `?`, but a wasm asset uses `?module` in its filename.
-
-**Fix:** Build/deploy on Linux (WSL, Codespaces, or CI).
-
----
-
-## Optional: Preview locally
-
-Preview the Worker locally before deploying:
-
-```bash
-npm run preview
-```
-
----
-
-## Summary
-
-| Feature | Without R2 | With R2 |
-|---------|------------|---------|
-| Cost | Free | Requires payment method |
-| ISR Caching | No | Yes |
-| Static Pages | Yes | Yes |
-| API Routes | Yes | Yes |
-| Setup Complexity | Simple | Moderate |
-
-Choose **without R2** for testing or simple apps. Choose **with R2** for production apps that need ISR caching.
