New features:
- Cloudflare-safe mode: per-container shield toggle that reduces spoofing to only vectors that don't trigger bot detection (canvas, audio, fonts, timezone, WebRTC) while keeping UA, platform, WebGL, and screen at real values to avoid consistency mismatches
- Preserve original tab: clicking a cross-domain link opens the target in a new container tab while keeping the original page open
- Cancel-based container assignment: navigations are cancelled synchronously before the tab leaves the current page, eliminating visual flash and duplicate tab issues

Performance:
- Removed blocking flag from onBeforeRequest (only observes main_frame, never modifies)
- Added types filter to onBeforeSendHeaders (main_frame, sub_frame, xmlhttprequest only) to reduce IPC overhead on heavy single-page apps

Bug fixes:
- Fixed duplicate tabs spawning on cross-domain navigation
- Fixed address bar searches opening multiple tabs
- Unified first-visit and existing-container code paths

This skips header spoofing on images, fonts, stylesheets, WebSockets, beacon, csp_report, etc.
