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
