Push builds have been RED on the lint step since ~build 209 from accumulated
formatting drift. This is the mechanical cleanup: ruff format + ruff --fix
(UP038 isinstance unions, SIM105 contextlib.suppress, UP031 f-strings, SIM115
tempfile context manager), shfmt -i 2 -ci, nixpkgs-fmt/statix/deadnix (merged
attrsets, dropped unused lib args), yamllint, and shell quoting fixes in
tests/lasuite-docs/setup_custom_tests.sh. No behaviour changes intended;
lint: PASS, unit tests: 138 passed.
PRAGMA busy_timeout=N emits its own result row, polluting the read-back parse (seed read back
'20000\nupgrade-survives' → AssertionError 'seed did not commit', failing upgrade/backup/restore ops
— though the INSERT actually committed). Switch _sqlite to 'sqlite3 -cmd ".timeout 20000"' which sets
the busy timeout silently. install+custom already green (handshake/welcome/web/tcp PASS); this fixes
the P4 lifecycle ops.
