Sync/dashboard, sanitize content, update config

Add local Claude permissions file; make background.js call syncToDashboard() after each run when config.syncToDashboard is enabled; improve content extraction in content.js by cloning link nodes, removing svg/style elements and stripping review-related text/counts before trimming; update config.py defaults to enable target and gamestop (remove bestbuy), set HEADLESS=True and STEALTH_HEADLESS=True to favor headless environments.
