feat(resolution): bridge Spring publishEvent() to its @EventListener handlers

Spring decouples an event publisher from its listener(s) through the
application event bus, linked by the event TYPE: publishEvent(new XEvent(...))
has no static edge to the @EventListener void on(XEvent e) that handles it
(usually a different class), so flows dead-end at the publish and the agent
reads to find the handlers. springEventEdges bridges each publishEvent(new X)
site -> every listener of X.

Two-pass, type-keyed (no name resolution, so precision is structural):
- Pass 1 builds Map<eventType, listenerMethod[]> from @EventListener /
  @TransactionalEventListener methods (event type = first param type off the
  node signature, or the @EventListener(X.class) value form) and the older
  `implements ApplicationListener<X>` onApplicationEvent methods.
- Pass 2 links each publishEvent(new XEvent(...))'s enclosing method to every
  listener of XEvent; multi-line `publishEvent(\n new X(...))` handled.

Key Java fact (probed): a method node's range INCLUDES its leading annotations
(startLine is the first @-line, not the `public void` decl), so the annotation
gate scans DOWNWARD from startLine bounded to consecutive @-lines, which can't
bleed into an adjacent method.

Surfaces as `dynamic: spring event` via the generic synth-edge fallback.

Validated 100% precision on two grep-confirmed repos exercising all listener
forms: halo (medium, 1254 java, 33 edges across 24 events, 0 publisher/listener
false positives, param-typed + (X.class) + ApplicationListener + fan-out) and
thombergs/code-examples (4 edges, adds @TransactionalEventListener); 0 on the
gson control (no Spring). Node-stable (pure edge synth). Suite 1617 green.

 - `codegraph_explore` now follows **Vuex** string dispatch. A `dispatch('user/login')` or `commit('SET_TOKEN')` call — namespaced `'module/action'` keys included — now links to the action or mutation it names, resolved to the correct store module even when several modules share an action name (and without being fooled by a same-named `api/` helper). So "what runs when this dispatches?" traces from the call into the store handler and on to the mutations it commits. Vuex's canonical `export default { namespaced, actions, mutations }` module shape is now indexed too, so those handlers are findable symbols.
 - `codegraph_explore` now connects React data-fetching flows built on **RTK Query** (Redux Toolkit's `createApi`). An endpoint defined inside `createApi({ endpoints })` and the `useGetXQuery` / `useUpdateYMutation` hook it generates were both invisible to analysis — so "what does this component fetch?" or "where does `useGetThingQuery` get its data?" dead-ended, because the hook, the endpoint, and the component had nothing linking them. CodeGraph now indexes each endpoint and each generated hook as real symbols and wires the path `component → useGetXQuery → getX → queryFn`, so the flow resolves in one explore call instead of reading the API slice by hand. Both the arrow (`endpoints: build => ({ … })`) and method (`endpoints(builder) { return { … } }`) styles are recognized, along with the `useLazyGetXQuery` variant; hand-written hooks of a similar name are left untouched.
 - `codegraph_explore` now follows **Celery** task dispatch in Python. A `send_email.delay(...)` or `send_email.apply_async(...)` call now links to the `@shared_task` / `@app.task` function it runs — typically defined in a different module (`tasks.py`) from where it's triggered (a view or service) — so "what actually happens when this is dispatched?" traces from the call site straight into the task body instead of stopping at the `.delay()` line. Both decorator dialects are recognized (bare `@shared_task` and the arg'd `@app.task(bind=True, …)` form), including the module-qualified `tasks.invalidate_cache.apply_async()` call style. It stays precise: a `.delay()` on something that isn't a Celery task is never mislinked, so a project that doesn't use Celery is unaffected.
+- `codegraph_explore` now follows **Spring application events** in Java. A `publishEvent(new OrderShippedEvent(...))` call now links to every `@EventListener` that handles that event — usually in a different class — so "what reacts when this is published?" traces from the publisher straight into each listener method instead of dead-ending at `publishEvent(...)`. The link is by event type, and all the common listener styles are recognized: a `@EventListener` typed on its parameter, the `@EventListener(SomeEvent.class)` form, `@TransactionalEventListener`, and the older `implements ApplicationListener<SomeEvent>`. One event fans out to all its listeners, and a plain Spring app with no event bus is unaffected.
 
 - `codegraph_explore` now surfaces the right code in large multi-layer projects. When you ask a backend-flow question in a repo that pairs an API server with a big frontend that mirrors the same domain words — say an `app/` admin UI sitting over an `api/` server — the server-side file that genuinely matches several of your query's terms is no longer pushed out of the results by the larger, more interconnected frontend layer. A file corroborated by two or more distinct query terms is now kept in the answer even when a denser unrelated layer would otherwise crowd it out, so "how does X read items / handle the request" returns the service or handler that does the work instead of a wall of frontend views. Single-layer projects are unaffected; set `CODEGRAPH_RANK_NO_MULTITERM=1` to revert to the previous ranking.
 - Impact and blast-radius analysis for TypeScript, JavaScript, Go, Python, Rust, Ruby, C, Java, C#, PHP, Scala, Kotlin, Swift, Dart, and Pascal/Delphi now understands the readers of a constant. When you change a file-scope, package-level, module-level, or class-level constant — a config object, a lookup table, a shared constant — the other symbols in that file that read it now show up as affected, where before they were invisible (impact only followed calls, imports, and inheritance, so a constant's consumers looked like "nothing depends on this"). This makes `codegraph impact`, and the impact trail in `codegraph_explore`/`codegraph_node`, catch the "change this table, break its readers" class of change. It's on by default and adds no nodes to your graph; bundled/minified files and ambiguously-shadowed names are skipped to keep results precise. Set `CODEGRAPH_VALUE_REFS=0` to turn it off.
