docs: deploying on Windows (#2500)

FrankenPHP runs natively on Windows since v1.12 (#2119), but the docs
don't mention it as a deployment target. This adds a "Deploying on
Windows" section to the production guide (install, running as a Windows
service with WinSW as [recommended by the Caddy
docs](https://caddyserver.com/docs/running#windows-service), graceful
reload) and a pointer to the Windows compilation instructions in the
compile docs.

Related to #2442. Follow-ups: #2501 (static/embed, see also #2503),
#2502 (macOS).

+## Deploying on Windows
+
+FrankenPHP runs natively on Windows, with full support for [the worker mode](worker.md) and [hot reloading](hot-reload.md).
+
+To install it, run this in PowerShell:
+
+```powershell
+irm https://frankenphp.dev/install.ps1 | iex
+```
+
+Alternatively, [download the Windows archive from the releases page](https://github.com/php/frankenphp/releases).
+It contains the FrankenPHP executable as well as the official PHP binary for Windows.
+
+To run FrankenPHP in the background and start it automatically at boot, register it as a Windows service.
+As [recommended by the Caddy documentation](https://caddyserver.com/docs/running#windows-service), use [WinSW](https://github.com/winsw/winsw):
+
+1. Download [the latest version of WinSW](https://github.com/winsw/winsw/releases) as `frankenphp-service.exe` in the directory containing `frankenphp.exe`
+2. In the same directory, create a `frankenphp-service.xml` file:
+
+   ```xml
+   <service>
+     <id>frankenphp</id>
+     <name>FrankenPHP</name>
+     <description>The modern PHP app server (https://frankenphp.dev)</description>
+     <executable>%BASE%\frankenphp.exe</executable>
+     <arguments>run --config %BASE%\Caddyfile</arguments>
+     <log mode="roll-by-time">
+       <pattern>yyyy-MM-dd</pattern>
+     </log>
+   </service>
+   ```
+
+3. Install and start the service:
+
+   ```powershell
+   .\frankenphp-service.exe install
+   .\frankenphp-service.exe start
+   ```
+
+Windows services cannot be reloaded. To apply configuration changes gracefully, without restarting the service, run:
+
+```powershell
+.\frankenphp.exe reload --config Caddyfile
+```
