fix(native): promote native this-dispatch scope tests from todo to active

The class-scoped this-dispatch fix (edge_builder.rs #1343) is now present
in the Rust source and compiled by CI for every PR. Remove the engine guard
that was skipping three negative assertions for native and the comment that
referenced the v3.11.2 binary gap.

All four this-dispatch-scope assertions now run for both wasm and native:
- emits Shape.describe → Shape.area (positive case)
- does NOT emit Shape.describe → Calculator.area (false-positive guard)
- does NOT emit Shape.describe → Formatter.area (false-positive guard)
- does NOT emit Caller.run → Sibling.area (single-match false-positive guard)

Closes #1413
