deno desktop 2.9.6 - signing error on laufey_webview with prod build using "-" signing option

Version: Deno 2.9.6
MacOS 12.7.6 Monterey M1

something in the build process has obviously been changed in 2.9.6 so now all prod builds are getting a signing error on laufey_webview. The app will still launch but the message of 'resource fork, Finder information, or similar detritus not allowed' is a bit disconcerting.

deno.json - as per docs and pre-2.9.6

"output": {
"macos": "./dist/DenoBasic.app",

Result on build with 2.9.6 -

% deno desktop -A main.js
⚠ deno desktop is experimental and subject to change
Compile main.js to ./dist/DenoBasic.app.dylib

Updated - removed .app in deno.json config but still get the signing error.

deno.json -

Typical result on 2.9.5 - using "macos": "./dist/DenoBasic.app",

Bundle DenoBasic.app

Note: also noticed that if I try to specify .dmg as the output the build process simply produces a .app bundle rather than a dmg image.

Start with the deno.json macOS output setting and main.js, then reproduce `deno desktop -A main.js` on Deno 2.9.6 and compare it with 2.9.5. Trace the desktop macOS bundle signing path around laufey_webview and verify whether the `.dmg` output behavior is related. Done means the production app bundle signs without the resource-fork error and the reported output behavior is clarified.
