Adds inline-expectation tests for the new shared CFG implementation in python/ql/lib/semmle/python/controlflow/internal/AstNodeImpl.qll, covering every Python binding construct that introduces a variable. The test files use MISSING: annotations to record bindings whose defining Name AST node is *not* currently reachable from the new CFG. These are the 'red' half of red-green commit pairs: subsequent commits will extend AstNodeImpl to cover each construct and remove the corresponding MISSING: marker. Confirmed-broken categories: - Import aliases (from x import a) - Annotated assignment (x: int = 1) - Exception handler (except E as e) - Match patterns (case x, case [a,b], case ... as v) - PEP 695 type params (def f[T], class C[T]) Confirmed-working (no MISSING:): - Compound targets, with-as, comprehensions, decorated def/class, walrus, starred.
