Test pin: ITensorActions reusables to the mf/subdir-inputs branch

Smoke test for ITensorActions#107. Pins the six reusables that PR
changes (or could affect) to its branch ref so SparseArraysBase's
CI exercises them with default inputs. Goal: confirm the new
inputs (`subdirs` / `extra-dev-paths` / `test-args` / `subdir`)
are purely additive and existing single-package consumers see no
behavior change.

Will close and revert this PR after observation. Not for merge.
