Lumo Copilot v0.2.4

Lumo Copilot v0.2.4 — proper installer window, and fewer security prompts.

The install window looks right again
v0.2.3 fixed the "damaged" error but built the DMG by hand, which lost the
styled drag-to-Applications window. Signing is now part of the normal build, so
you get the correct installer and a valid signature.

About the security warnings after v0.2.3
macOS ties an app's granted permissions to its code signature. v0.2.3 was the
first build with a real signature, so macOS treated Lumo as a brand-new app and
asked for everything again. That was a one-time consequence of the fix.

The app's identity is now stable (com.lumocopilot.app), so permissions stick
from here. You may still get a prompt after an update — unavoidable without a
paid Apple certificate — but not the flood you just saw.

First launch, if you're installing fresh
Double-click, let macOS refuse it, then System Settings → Privacy & Security →
Open Anyway. Once only.

No functional changes — same app as v0.2.2, correctly packaged.
