ygd58 74c1b946e0 fix(browser): inject --no-sandbox for root and AppArmor userns restrictions ...

On VPS/Docker and some Ubuntu 23.10+ hosts, Chromium refuses to start
without --no-sandbox:
  - uid=0 (root): hard requirement (VPS/Docker deployments)
  - AppArmor apparmor_restrict_unprivileged_userns=1 (Ubuntu 23.10+):
    non-root too, under systemd or unprivileged containers

Detect both conditions and inject AGENT_BROWSER_CHROME_FLAGS with
--no-sandbox --disable-dev-shm-usage when the user hasn't already
set the flags themselves.

Salvage of #15771 — only the browser_tool.py fix is cherry-picked.
The PR's accompanying MCP preset addition (new feature surface)
was dropped so the bug fix can land independently.
