Ubuntu/AppArmor configurations often block unprivileged Chromium sandboxing
for headless agent sessions even for normal users — /qa hangs without
--no-sandbox. The kernel policy denies the unprivileged user namespaces
Chromium needs.
Adds GSTACK_CHROMIUM_NO_SANDBOX=1 as an explicit user override that forces
the sandbox off without changing the default for everyone else. Re-authored
from PR #1562 onto v1.42.2.0's shouldEnableChromiumSandbox() helper —
purely additive, preserves the headed-launch sandbox-on-by-default behavior
that v1.42.2.0 shipped to kill the --no-sandbox yellow infobar.
Three new regression tests cover:
- linux + override=1 → false (the named use case)
- darwin + override=1 → false (env wins on any platform)
- override=0 → does NOT trigger (must be exactly "1")
