The `UpvalueAnalyzer` now correctly identifies which lambdas capture which variable declarations, rather than just marking declarations that need boxing. This information is stored in a `capture_map`. The `Binder` has been updated to use this new `capture_map` instead of a `HashSet` of boxed declarations. The `DefLocal` node in `bound_nodes.rs` now stores a `captured_by` field, which is a list of lambda identities that capture the local variable. A new `dumper` module has been added to provide a human-readable representation of the bound AST, including information about captured variables. The `VM` has been updated to use the `captured_by` field to determine if a local variable needs to be stored in a `Cell`, rather than relying on a boolean `is_boxed` flag. An example script `extreme_capture.myc` has been added to test deep nesting and variable capture. A new "Dump AST" button has been added to the UI, which uses the new `Dumper` to display the bound AST.
