changed: an edit inside a multi-line const initializer is that const's

[swapnilpaliwal-sd]

• An edit, inserted member, removed line or comment on a later line of a const/field whose initializer spans lines (a schema builder's object, an `as const` token table, a multi-line static initializer) was `body ` / `inside `, so test-impact seeded from the whole module. It is now `field X — initializer changed`.
• A data key of a const object (now a declaration) edited in place was `type 3, → 4,`, and on a one-line const `LIMIT.max renamed → LIMIT`. It is now the key's `initializer changed`; a removed key is `removed`.
• A method or lambda written inside the initializer keeps its own body; a Python module-level name is measured by its statement.
• Cases: typescript/multi-line-initializer (8 checks incl. 3 controls: one-line const, object-literal method, function below), plus one check each for JS, Python, Java, C#. Without the fix, 6 of the 8 TS checks fail.
• Checked: case suites TS 233/233, JS 286/286, Python 290/290, Java 330/330, C# 208/208. On a 74-probe TS monorepo: 52/74 pass (the loop's baseline engine: 47), no regressions; a one-property edit to each of three multi-line consts now names the const.
