Latest electron-builder install still emits inflight/glob/rimraf deprecation warnings

Nobody has claimed this yet.

### Environment

- `electron-builder`: 26.15.3 (latest when tested)
- npm on GitHub-hosted Node 22 runners

### Reproduction

```sh
npm install --no-audit --no-fund
```

with `electron-builder` in devDependencies emits deprecations for `inflight@1.0.6`, `glob@7.2.3`, and `rimraf@2.6.3`. `npm ls` traces them through electron-builder packaging dependencies (including `app-builder-lib` / `@electron/asar` and `electron-winstaller`). A public CI reproduction is https://github.com/link-assistant/formal-ai/actions/runs/29465138404.

### Expected

Installing the current supported release on Node 22 should not emit deprecations from transitive dependencies.

### Suggested fix

Upgrade or replace the legacy glob/rimraf dependency chains; consider making platform-specific makers optional so NSIS-only consumers do not install the Windows Squirrel toolchain.

Start by running npm install --no-audit --no-fund and npm ls with electron-builder 26.15.3 on Node 22, then trace the reported inflight, glob, and rimraf chains through app-builder-lib, @electron/asar, and electron-winstaller. Done means the supported installation no longer emits these deprecations, with platform-specific maker dependencies considered separately.
