Pull request #1960: PIPE-3237: optimize unflagged data checks in `hif_findroi` and `ImageParamsHeuristics`
Merge in PIPE/pipeline from PIPE-3237-hif_findroi-very-inefficient-for-cases-with-many-fields-x-eb-x-spw to main
* commit '82fe783a77d453ed5300b9485da639fd9933cecc': PIPE-3237: warn once when `hif_findroi` skips a virtual spw PIPE-3237: simplify target field name list construction in `findroi.py` PIPE-3237: optimize unflagged data checks in `hif_findroi` and `ImageParamsHeuristics`
PIPE-3237: optimize unflagged data checks in `hif_findroi` and `ImageParamsHeuristics`
- Deduplicate target field names in hif_findroi using utils.deduplicate to avoid redundant probes across mosaic pointings
- Short-circuit the EB/field probe loop in hif_findroi as soon as unflagged data is confirmed for an SPW
- Break early in ImageParamsHeuristics.has_data once valid data is found for a field intent
