Runs the test suite, format check, unused-deps check, and warnings-as-errors compile across Elixir 1.19/OTP 28 and 1.20/OTP 29. The Oils-format conformance spec suite (which tracks known gaps against reference Bash) runs in a separate, non-blocking job that reports its pass/fail count to the job summary.

The test interpolated the tmp_dir path into an unquoted redirect target. On Elixir 1.19+, ExUnit's tmp_dir name includes the test description verbatim, which for this test contains "(-C)" — and unquoted parentheses are shell-special, so the redirect misparsed (exit 127, no error output) rather than triggering noclobber. Real Bash would fail on the unquoted path too. Quote the redirect target so the path is treated literally, and read stderr via the session's persistent collector (flush_session_output/1) rather than the result-embedded collector, which is transferred and cleaned up asynchronously after execution.
