ignite new --remove-demo has no effect: demo code is still generated (11.5.0)

Describe the bug

ignite new <App> --remove-demo generates a project with all the demo code still in it. The flag appears to be parsed as false regardless of how it's passed — the CLI's own "here's the command to reproduce this" block, printed at the end of a successful run, echoes --remove-demo=false even when --remove-demo or --remove-demo=true was supplied.

Both forms reproduce it:

npx ignite-cli@latest new ReproBare --yes --remove-demo      --install-deps=false --git=false --no-timeout
npx ignite-cli@latest new ReproTrue --yes --remove-demo=true --install-deps=false --git=false --no-timeout

Expected: demo screens, the demo navigator and demo assets are not generated.

Actual: both projects are byte-for-byte identical in file listing to a run with --remove-demo=false — 95 files under app/:

The markup half does run — ️ Removing fancy demo markup is logged, and the generated tree contains no @demo comments. It's the file/directory removal that doesn't happen.

Running the standalone command afterwards doesn't recover it either — npx ignite-cli remove-demo --dry-run inside the generated project reports only the two demo asset directories, not the screens or the navigator.

Because the @demo markup has already been stripped at generation time, the standalone remove-demo no longer has the anchors it would need to find that code, so the two failures may share a root cause.

Found while running an unrelated experiment (#3041) that needed a demo-free project; I ended up stripping the demo by hand. Happy to dig into the flag parsing and open a PR if that's useful.
