daemora.iss

; Daemora Windows installer (Inno Setup 6+)
;
; Build:   iscc installer\windows\daemora.iss
; Output:  installer\windows\Output\DaemoraSetup.exe
;
; What this does at install time:
;   1. Detect Node.js >= 22. If missing, install via winget; fall back
;      to downloading the official Node 22 MSI from nodejs.org.
;   2. Run `npm install -g daemora`.
;   3. Drop launcher.ps1 + assets into the install dir.
;   4. Create Start Menu + Desktop shortcuts that run the launcher
;      silently (no PowerShell window).
;   5. Optionally launch Daemora at the end of setup.
;
; Lifecycle: the launcher spawns `daemora start` as a detached, hidden
; process and writes its PID to %APPDATA%\Daemora\daemora.pid. Closing
; the browser, the launcher, or signing out of Windows leaves the
; daemon running until the user picks "Stop Daemora" or reboots.
