Sebastian Graf 0007ffa16a refactor: simplify mkBackwardRuleForSplit and fix fvar alt handling 
Inline `withSplitterAndLocals` into `mkBackwardRuleForSplit` and replace it
with a single `SplitInfo.splitWith` call. Eta-expand alts in `withAbstract`
so `matcherApp.transform` can `instantiateLambda` them directly (no patching
needed), then eta-reduce when computing `abstractProg` to avoid expensive
higher-order unification in backward rule patterns. Extract `mkGoal` and
`extractProgFromGoal` as top-level helpers, removing `replaceProgInGoal`.
