  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. It puts the watcher repo in %USERPROFILE%\eve-watcher, forces the
  working tree to match the latest code, and runs update.py - which installs deps +
  Tesseract, starts the watchers, auto-detects the ore-hold readout (no manual snip),
  and registers logon + daily auto-update. You never have to install or update again.

  Safe to re-run anytime: it force-syncs to the latest code (reset --hard) and never
  touches your gitignored config.ini.
