LUTE workflow milestone — complete

The LUTE smalldata workflow for xcs101591326 (sub-issue #92) is set up and producing data end-to-end, so the data-reduction foundation for the polariton analysis is in place.

• LUTE deployed; config at /sdf/data/lcls/ds/xcs/xcs101591326/results/lconreux/lute_output/xcs_lute.yaml.
• Smalldata produced for 378 runs (Run0001–Run0392) under /sdf/data/lcls/ds/xcs/xcs101591326/hdf5/smalldata/.
• Detectors epix10k2M, epix_1, epix_2; epix_2 ROI + detSumAlgos (calib, calib_dropped, calib_dropped_square, calib_thresADU1); DCCM PVs under epicsUser/.
• Producer/template bugs fixed along the way (epicsPV list→tuple coercion, epicsArchFilePV→epicsPV rename, YAML indentation, run-4 config syntax error). Full detail and HDF5 verification in xcs101591326 LUTE workflow setup #92.

This closes the LUTE-setup portion of this experiment's work (and the XCS side of #78). Remaining polariton analysis items continue to be tracked here.
