Headless browser (Playwright):
- New: headless_browser.py — full Playwright-based browser implementation
- Supports: navigate, screenshot, get_text, click, type, evaluate, get_elements
- Auto-fallback: execute_browser_tool tries Electron webview first, falls back to
headless Playwright when "not found" error detected
- Works everywhere: web browser, Electron app, server, CI
- Pages managed per browser_id, cleaned up on session close
WebSearch fix:
- Changed User-Agent from bot identifier to Chrome UA
- DDG serves different HTML to bots vs browsers, causing parse failures
- Now returns proper results (tested: Eater SF, Infatuation, etc.)
Requirements:
- Added playwright to requirements.txt
