What

Prefer Firefox for desktop_open_url when installed.
Keep Falkon and Chrome/Chromium as fallbacks.
Size Firefox/Falkon windows deterministically after launch.
Bump runtime to 0.3.5.

Why

Live display debugging showed Chrome, Falkon, and Epiphany could open windows under Xvfb, but browser page surfaces stayed gray. Firefox under Xorg dummy rendered Example Domain content correctly, so runtime should prefer the browser that works with the display backend.

Verification

PYTHONPATH=$PWD pytest tests/test_desktop_tools.py -q -> 8 passed
PYTHONPATH=$PWD pytest -q -> 369 passed
Live workspace proof on i-0b44c4a365494ba9d: Firefox on Xorg dummy rendered Example Domain content in screenshot /tmp/firefox-xorg-thumb.jpg.

Reviewed five-axis pass: correctness OK based on local full suite and live Xorg/Firefox rendering proof; readability/architecture OK (narrow browser preference/display backend changes); security OK (URL remains argv, no shell, display remains localhost-only); performance OK for display-enabled workspaces only. Gitea checks are Waiting with no action_task rows, so approval is based on direct verification.
