setup.ps1

#Requires -Version 7.0
<#
.SYNOPSIS
  One-shot setup for Anya — GitHub Copilot for your browser.

.DESCRIPTION
  Cross-platform PowerShell 7+ installer. Installs deps + builds both
  projects, runs the bridge ping smoke test, and registers the Native
  Messaging host for every detected Chromium browser (Edge, Chrome,
  Chromium, Brave, Vivaldi, Arc).

  Works on Windows, macOS, and Linux. For users without pwsh, an
  equivalent setup.sh is provided.

.PARAMETER Browsers
  One or more of: edge, chrome, chromium, brave, vivaldi, arc, all (default).
  Forwarded to bridge\install.ps1.

.PARAMETER Quiet
  Skip the interactive browser picker when multiple Chromium browsers are
  detected (registers for all of them).

.PARAMETER SkipTest
  Skip the bridge ping/pong smoke test.

.PARAMETER Uninstall
  Remove every browser's registration + manifest, then exit.
