Description

After upgrading macOS to Tahoe 26.6, when I launch Harper Desktop, I get the message in the screenshot below: "Apple could not verify “Harper.app” is free of malware that may harm your Mac or compromise your privacy." My Harper Desktop version is 2.7.0. macOS is in Lockdown Mode. I installed Harper Desktop via `brew install harper-desktop` to `$HOME/Applications` instead of the usual `/Applications`. I did not have this issue on Tahoe 26.5, but I don't want to draw premature conclusions.

Let me know if I can provide information to help maintainers debug this issue. Thank you for your time.
