Add a shared CEF installer that downloads, verifies, and manages CEF binary distributions on Windows. The installer is embedded in application bootstrap binaries and resolves the correct CEF version from a CDN manifest based on each application's version and ABI compatibility requirements. Key components: - CDN manifest parsing and version resolution - WinHTTP-based download with SHA-1/SHA-256 integrity verification - Authenticode catalog (.cat) signature verification - Parallel XZ decompression for fast archive extraction - Per-version metadata (cef_version.json) with full version tracking - Shared installation database for multi-app version management - Version pruning to reclaim disk space from unused versions - Revocation list support (compiled-in baseline + CDN delta) - Progress UI with WM_COPYDATA-based cancellation - Bundled CEF fallback for offline/CDN-failure scenarios
