This PR adds support for incrementally processing local declarations in `grind`. Instead of processing all hypotheses at once during goal initialization, `grind` now tracks which local declarations have been processed via `Goal.nextDeclIdx` and provides APIs to process new hypotheses incrementally. This feature will be used by the new `SymM` monad for efficient symbolic simulation.
