ci(bundle): publish portable Windows and macOS desktop packages

Build and check Bundle alongside each native compiler. Publish a single
Windows exe with an embedded compiler extracted into the startup directory,
and a macOS tar.xz containing the app and compiler. Check Linux without
publishing a desktop package and require all six nightly attachments.

Include licenses in embedded assets and app resources. Verify local builds,
package smoke checks and release replacement with a simulated GitHub API.
