ci: add macOS and Windows debug build jobs (D1)

Add build-macos and build-windows CI jobs that run flutter build
for each platform after the main check suite passes on main.

Both jobs use FVM to install the pinned Flutter version and run
codegen before building. They require platform-specific runners
labelled 'macos-latest' / 'windows-latest'; the jobs are skipped
automatically if no matching runner is registered.
