Validates the python heredoc inside `local/scripts/cleanup-kf6-noop-seds.sh`. The heredoc is the meat of the script — it walks each `sed -i ...` line plus any `\\` or `&& cd ...` continuations and deletes them as a single chain. The test fixtures cover: - single-line sed - multi-line sed with `\\` continuation - chained seds with `&& cd ...` continuations - no-sed baseline (text unchanged) - actual kf6-attica recipe excerpt (5 sed lines, all gone) Also adds TestScriptStructure checks: - script exists and is executable - script lists all 24 NO-OP recipes - script makes a timestamped backup - script handles `\\` continuations Makefile: - new `test-cleanup-noop-seds` target - added to `lint-build-system-all` aggregate - .PHONY target list updated 132 Python tests total (was 124, +8 new). All 8 test files pass in <1s.
