tests: drop the serial [large] test (serial dataset not shipped)

Only the ~1800-image rotation dataset is kept in LFS; a separate ~5000-image serial set is too
large to ship, and the serial path can be exercised by running the rotation series in serial
mode if needed. Removes JFJochProcess_LysoSerial and the serial entry from the start-up listener
and README. The rotation [large] test now runs against the committed data and passes.

-To point the tests at an existing local dataset without copying, symlink it:
-
-```
-ln -s /path/to/your_master.h5            tests/data/lyso_rotation_master.h5
-ln -s /path/to/your_data_000001.h5       tests/data/...
-```
-
-(The master references its data files by relative name, so keep them side by side.)
+`lyso_rotation_master.h5` (plus its `_data_NNNNNN.h5` files) is fetched by `git lfs pull` and
+drives `JFJochProcess_LysoRotation`. A separate serial dataset is intentionally **not** shipped
+to keep the repository small — the rotation series can be run in serial mode (full analysis
+without rotation indexing) to exercise that path. To add your own dataset, drop the master + its
+data files here as real files (not symlinks, if you intend to commit them via LFS); the master
+references its data files by relative name, so keep them side by side.
