Bring the checklist app under version control

The project has lived only as a folder on the Mac Studio and, briefly, as a
transfer tarball. This is the first commit: the Express server and its web
front end, the Capacitor iOS and Android wrappers, and the release and backup
scripts.

The repo is the source, not a backup of the machine. Left out on purpose, by
the .gitignore files that were already in the tree: node_modules, build output,
mobile/www (regenerated from server/public on every build), and server/data,
which holds the live checklists and belongs on the NAS rather than in git.

Every credential is excluded too — server/.env, the Play upload keystore and
its properties file, the App Store Connect key and ios-signing.config. The one
secret that was not in an ignored file was the NAS SSH password, hard-coded in
build-deploy.sh and grepped back out of it by backup-to-drive.sh. Both now read
it from the login keychain (service checklist-nas, account Christian), falling
back to NAS_PASS in the environment, so rotating it is one keychain entry
rather than a history rewrite.

+- ✅ Set items to recur daily, weekly, or monthly
+- ✅ Automatic reset of recurring items based on schedule
+- ✅ Dark theme interface matching Planning Center style

+
+## Installation
+
+### Development Setup
+
+1. Install Node.js (if not already installed) - Download from [nodejs.org](https://nodejs.org/)
+2. Navigate to the project directory:
+   ```bash
+   cd recurring-checklist-app
+   ```
+3. Install dependencies:
+   ```bash
+   npm install
+   ```
+4. Run the application:
+   ```bash
+   npm start
+   ```
+
+### Building for Windows Distribution
+
+To create a Windows executable installer:
+
+```bash
+npm run build:win
+```
+
+This will create an installer in the `dist` folder that you can distribute to other machines. The installer will be named something like `Recurring Checklist Setup 1.0.0.exe`.
+
+## Usage
+
+1. **Add Tasks**: 
+   - Enter a title (required) and optional description
+   - Descriptions support multiple lines and can include detailed instructions
+   - Click "Add Task" or press Enter
+
+2. **Set Recurrence**: 
+   - Check "Recurring Task" checkbox
+   - Select frequency: Daily, Weekly, or Monthly
+   - For weekly: Choose the day of the week (e.g., Sunday)
+   - For monthly: Choose the day of the month (1-31)
+
+3. **Complete Tasks**: 
+   - Check the checkbox next to an item to mark it complete
+   - Completed items automatically move to the "Done" section
+
+4. **Recurring Reset**: 
+   - Recurring items automatically reset based on their schedule
+   - Daily items reset each day
+   - Weekly items reset on their specified day
+   - Monthly items reset on their specified day of the month
+
+5. **Delete Tasks**:

+- **Weekly**: Item resets on a specific day of the week (e.g., every Sunday)
+- **Monthly**: Item resets on a specific day of the month (e.g., day 1)
+
+## Data Storage
+
+All checklist data is stored locally on your machine using `electron-store`. Data persists between application sessions and is stored in your user data directory.
+
+## Distribution
+
+The built application can be easily copied to other Windows machines:
+
+1. Build the installer using `npm run build:win`
+2. Copy the installer file from the `dist` folder
+3. Run the installer on each Windows machine where you want to use the app
+4. Each installation will have its own independent data storage
+
+## Requirements
+
+- Windows 7 or later
+- Node.js (for development and building only)
+
+## Notes
+
+- The application checks for recurring items every minute
+- Recurring items reset based on the current date/time
+- Each machine will have its own separate checklist data
+- The app uses a dark theme similar to Planning Center for better visibility
