#Requires -Version 5.1
<#
.SYNOPSIS
    Build and run the CodexBar Tauri desktop shell for Windows.

.DESCRIPTION
    Checks that build prerequisites are installed, then builds the Tauri desktop
    shell through the Tauri CLI and launches it.

.PARAMETER Release
    Build in release mode (optimised). Default is debug.

.PARAMETER SkipBuild
    Skip the build step and run the last built binary.

.PARAMETER Verbose
    Enable debug logging via RUST_LOG for the Tauri desktop shell.

.EXAMPLE
    .\dev.ps1                  # debug build + run
    .\dev.ps1 -Release         # release build + run
    .\dev.ps1 -SkipBuild       # run last build
    .\dev.ps1 -Verbose         # debug build + run with verbose logging
