Found by the P10 fresh-VM run: `simurg inspect … | head` raised BrokenPipeError, reported as
an internal error, and stopped examples/gsa_demo.sh (set -o pipefail). run_guarded now flushes
stdout inside the guard and maps BrokenPipeError to ExitCode.SIGPIPE (141) without a message.
p10.sh: SKIP_DOCKER/SKIP_CONDA, clearer digest report; p10t.sh runs build+pip+tutorial only.
docs/user_guide.md (install, inputs, complete run, commands, presets, QC, outputs,
accuracy, limitations, troubleshooting), examples/gsa_demo.sh (end-to-end run on the
public GSA demo, verified on the Pi), examples/sample_sheet.csv, CHANGELOG.md; version 1.0.0.
