fix: update workflow to generate correct formula class name

Critical fixes:
- Change class name from 'Warp' to 'WarpCli' to match filename
- Add cask dependency (cloudflare-warp) so daemon is auto-installed
- Add post_install hook to remove GUI app
- Add version attribute
- Improve caveats message with checkmarks

This fixes the Homebrew error:
  'Expected to find class WarpCli, but only found: Warp'

Now users can successfully run: brew install warp-cli

-                Cloudflare WARP app must be installed first:
-                  brew install --cask cloudflare-warp
+                ✅ WARP daemon installed and configured
+                ✅ GUI app removed (not needed for CLI)
 
-                Or download from: https://apps.apple.com/app/cloudflare-warp/id1423210915
+                Your WARP daemon is running. Try it:
+                  warp up          # Connect to WARP
+                  warp status      # Check connection
