- add a dedicated `compiler/destructuring_planner` feature that precomputes binding plans for assignments, parameters, and `some in` expressions - enrich `ScopeContext` with same-scope tracking, local scheduling hints, and module globals so the planner enforces := shadowing rules without blocking parent scopes - wire the planner through compiler, hoist, interpreter, and engine paths while updating binding plan variants and adding query traversal helpers for dependency analysis - document the new planner architecture and ship interpreter regressions that exercise nested destructuring, shadowing, and error reporting Signed-off-by: Anand Krishnamoorthi <anakrish@microsoft.com>
