Workarounds
• Disable or unregister electerm protocol handlers (Deep Link settings) and avoid clicking `electerm://` links.
• Do not run electerm with untrusted `--opts` arguments or open `.lnk` / `.desktop` files from untrusted sources.
• Restrict which users can launch electerm on shared machines and avoid leaving electerm installed in locations reachable by other users.
• As a temporary measure, run electerm in a confined account or sandbox (non-admin user) to reduce impact.
