  install.ps1 — first-time bootstrap for the Eve watchers (Goliath + Adam's PC).

  One-liner (PowerShell):
    irm https://git.armoredarmadillo.com/brockdarnold/eve-watcher/raw/branch/main/install.ps1 | iex

  Paste it ONCE and you're done forever: it puts the watcher repo in
  %USERPROFILE%\eve-watcher, runs update.py, and update.py registers a Windows
  Scheduled Task that auto-updates + restarts the watchers at every logon and
  once a day. You never have to install or update again.

  Safe to re-run: if the folder already exists (even from the old non-git
  installer) it is converted into a git clone in place, keeping your config.ini
  (webhook + OCR snip). config.ini is gitignored, so updates never touch it.
