Adrià Arrufat 2e2cdc2927 fix(browser): claim the Chrome-fallback socket dir before using it
_run_chrome_fallback_command creates agent-browser-<session> in the shared
tmpdir and then opens stdout/stderr files inside it, but never writes the
<session>.owner_pid marker. _reap_orphaned_browser_sessions rmtree's any
agent-browser-* dir that carries no live owner and is not tracked in the
calling process, so a second hermes process — or a parallel test worker —
deletes the directory between the makedirs and the first os.open, and the
command dies with FileNotFoundError on _stdout_open.

Write the owner marker immediately after creating the directory, which is
what every other socket-dir user already does.

Deterministic repro on main: run any test that exercises the fallback while
a second process calls _reap_orphaned_browser_sessions() in a loop —
5/5 fail before, 6/6 pass after.
