…of Dynamic Task Map (#62287) * fix: use parent's map_index for XCom lookup in NotPreviouslySkippedDep When an unmapped SkipMixin parent (e.g., LatestOnlyOperator) is upstream of a dynamically mapped task, the child task must look up XCom using map_index=-1 (the parent's XCom storage index) rather than the child's own map_index. This fix ensures mapped downstream TIs are correctly skipped when appropriate. Fixes #62118 * fix: apply ruff formatting and import sorting - Split long multi-argument function call across lines - Fix import order: move XComModel import before providers * ci: trigger CI re-run (transient docs build cache failure) (cherry picked from commit 41d897f) Co-authored-by: Stanislav Chernov <bintocher@yandex.com>

fix: use parent's map_index for XCom lookup in NotPreviouslySkippedDep
When an unmapped SkipMixin parent (e.g., LatestOnlyOperator) is upstream
of a dynamically mapped task, the child task must look up XCom using
map_index=-1 (the parent's XCom storage index) rather than the child's
own map_index. This fix ensures mapped downstream TIs are correctly
skipped when appropriate.
Fixes LatestOnlyOperator not working if just before a Dynamic Task Mapping #62118
fix: apply ruff formatting and import sorting
(cherry picked from commit 41d897f)
