fix: default strict_setup_readiness to False to avoid false infra failures

The post-setup focus check (PR #107) defaults to strict mode, which
marks tasks as infrastructure failures when the a11y window enumeration
can't find the expected app title. In practice, LibreOffice windows
take longer to render titles than the check allows, causing ALL
LibreOffice tasks to fail as infra — even though the app IS open.

Changing default to False: focus check still runs and logs warnings,
but doesn't abort the task. The agent can recover from focus issues
on its own (it did in all prior trials without this check).

Use --strict-setup-readiness to opt into the fatal behavior when
the a11y detection is more reliable.
