tests: git-LFS large-dataset harness + jfjoch_process include cleanup

- .gitattributes tracks tests/data/*.h5 via git-LFS for big reference datasets.
- tests/TestData.h resolves tests/data files and reports absent / unfetched-LFS-pointer
  so tests can SKIP() instead of failing; tests/data/README.md documents fetching + the
  expected lyso_rotation/lyso_serial datasets.
- JFJochProcessLargeTest: a Catch start-up listener that prints dataset availability, plus
  [large] full-analysis runs (rotation indexing + serial) that SKIP when data is absent.
  Verified against the real 1800-image lyso rotation set (100% indexing, cell 78.2/78.2/37.8)
  and skips cleanly without it.
- jfjoch_process.cpp: drop the ~15 now-unused workflow includes left after the JFJochProcess
  extraction.
