v0.2.2: fix malformed ad-hoc signature on macOS DMG

Set bundle.macOS.signingIdentity = "-" so Tauri runs codesign --force --deep
after assembling the .app, properly sealing Resources/ and Info.plist.

Before: linker-only signature, "Sealed Resources=none", spctl rejected with
"code has no resources but signature indicates they must be present" — Mac
users got the harshest "MDHero is damaged" Gatekeeper dialog and couldn't
work around it with right-click → Open.

After: proper ad-hoc signature with Sealed Resources v2 (verified locally
via codesign -dv + codesign --verify --deep --strict). Gatekeeper still
rejects (no Developer ID; that requires the $99/yr Apple Developer Program)
but with the friendlier "Apple cannot verify..." dialog that *does* allow
the right-click → Open workaround.
