fix(ui): count module-level initializer calls as the file's top-level code

Walking a declaration's initializer attributes its calls to the declared
name, so `const service = new Service()` no longer leaves a calls edge on
the FILE node — and the viewer's entry points ranking and the file screen's
top-level count, which read only the file node's edges, went blank on
exactly the files that run the most. Count a module-level variable or
constant's calls with the file in both places.

 - Python module-level assignments now contribute the calls their right-hand side makes — `app = FastAPI()`, `ENGINE = create_engine(url)`, `handler = lambda: run()`, a registry dict or list of handlers. Previously everything a module wires up at import time was missing from the graph, so the objects it builds looked unreferenced. Re-index with `codegraph index -f` after upgrading to pick up the new edges.
 - Rust `const` and `static` initializers now contribute their calls: `static REGISTRY: Lazy<Cfg> = Lazy::new(|| build())`, `const LEN: usize = compute_len()`. Previously anything a lazily-built singleton or a computed constant called was missing from the graph entirely. Re-index with `codegraph index -f` after upgrading to pick up the new edges.
 - Scala `val`/`var` definitions now contribute the calls their initializer makes — `val handler = () => process(msg)`, `val client = buildClient()`, `lazy val engine = start()`. Previously everything on the right-hand side was dropped, which on a val-heavy codebase (SpinalHDL hardware descriptions, Akka wiring) is most of the wiring: a 32-file SpinalHDL project gained 812 references it had been missing. Re-index with `codegraph index -f` after upgrading to pick up the new edges.
-- TypeScript and JavaScript module-level declarations now name themselves as the caller of whatever their initializer runs. `const cfg = loadConfig()` recorded the *file* as loadConfig's caller, which is no use for callers or impact; it now records `cfg`. And an object literal that wasn't exported — `const handlers = { onSave: () => persist() }` — was skipped entirely, so nothing inside it reached the graph at all. Re-index with `codegraph index -f` after upgrading to pick up the new edges.
+- TypeScript and JavaScript module-level declarations now name themselves as the caller of whatever their initializer runs. `const cfg = loadConfig()` recorded the *file* as loadConfig's caller, which is no use for callers or impact; it now records `cfg`, and the viewer's entry points and file screens still count that call as the file's top-level code. And an object literal that wasn't exported — `const handlers = { onSave: () => persist() }` — was skipped entirely, so nothing inside it reached the graph at all. Re-index with `codegraph index -f` after upgrading to pick up the new edges.
 - `codegraph_explore` again lists a dynamic-dispatch link when the same two symbols are also joined by an ordinary call, instead of dropping it from the summary.
 - Java fields initialized with a lambda or an anonymous class — `private final Runnable r = () -> doWork();`, `new LocationListener() { … }`, `Parcelable.Creator` — now contribute call edges, and the anonymous class and its overrides become real symbols instead of being invisible. Previously everything inside a field initializer was dropped, so a method reached only from one looked like it had no callers. Re-index with `codegraph index -f` after upgrading to pick up the new edges.
 - Kotlin `init { }` blocks and destructuring declarations no longer swallow their code: `init { val cfg = load() }` and `val (a, b) = makePair()` contributed no call edge at all, and now attribute to the enclosing class or file.
