Still need to figure out if there is a way to make the generic factor ext trait able to express more complicated validation logic as in |

Ok so it seems like we need to delete the scalar function factory ext |

Uses `ScalarFnFactoryExt` for tensor and geo scalar functions instead of maintaining per-function constructors. `L2Denorm` keeps its checked constructor because it validates the normalized-row invariant. Signed-off-by: "Connor Tsui" <connor.tsui20@gmail.com>

(semi-related) Tracking Issue: #9129
Right now the tensor and geo scalar functions maintain bespoke inherent constructors alongside
ScalarFnFactoryExt::try_new_array. This removes the redundant constructors and migrates the in-tree callers to the shared factory API.Note that this intentionally removes public
new()andtry_new_array(...)methods fromCosineSimilarity,InnerProduct, andL2Norm, plustry_new_array(...)from the four geo scalar functions. This is a source compatibility break, which is why I split it out from the RowFn work and left the PR as a draft. The main review question is whether the smaller and consistent API is worth that break, or whether these should remain as forwarding methods.Normalizedused to be the awkward exception here: its constructors enforce or explicitly bypass the normalized-row invariant, which the generic factory cannot express. That turned out to be a sign it was never a scalar function in the first place, so it moves to a dedicated array encoding in #9138 and is no longer part of this diff.
