Fix Install split_tests: gunzip -f to allow re-running in the same job - #18

Conversation
gunzip refuses to overwrite an existing output file without -f. That's fine for a single invocation, but any workflow that calls this action more than once in the same job/workspace (e.g. smoke-test-correctness in #15, which calls it 3x to test 3 partitions) hit: gzip: split_tests already exists; not overwritten ##[error]Process completed with exit code 2 introduced when #12 switched from 'curl | gunzip -v > split_tests' (unconditional overwrite via shell redirection) to 'gunzip -v split_tests.gz' (in-place decompress, which gunzip won't clobber by default).

Adds smoke-test-correctness: runs the default file-count split across all three split-index values with split-total=3, then asserts partitions are non-empty, pairwise disjoint, and their union covers the full glob exactly. Closes the repo's own long-standing 'Test output for correctness' TODO. Its own CI run also caught two real regressions along the way (JUnit ruby-version bug from #6 -> fixed in #17; gunzip overwrite bug from #12 -> fixed in #18).

gzip: split_tests already exists; not overwritten(exit code 2) — which is exactly what #15's new smoke-test-correctness job does (invokes the action 3x to test 3 partitions). Regression from #12, which switched fromcurl | gunzip -v > split_tests(unconditional overwrite via shell redirection) togunzip -v split_tests.gz(in-place, won't clobber by default). One-flag fix.
