Adds the RTK Query member of the dispatch-through-indirection family
(synthesizedBy:'rtk-query'). An RTK Query endpoint defined inside
`createApi({ endpoints })` and the `useGetXQuery`/`useUpdateYMutation` hook it
generates were both invisible to static extraction, so a `component →
useGetXQuery → getX → queryFn` flow had nothing to connect and explore
dead-ended on the API slice.
Extraction (tree-sitter.ts): mint a function node per endpoint — named by its
key, spanning the queryFn/query handler so its calls attribute — handling both
the `endpoints: build => ({...})` arrow and `endpoints(builder){ return {...} }`
method forms, with a bare-node fallback for factory handlers
(`queryFn: makeFn(url)`); and a function node per generated-hook binding from
`export const {...} = api`, carrying a sentinel signature.
Resolution (callback-synthesizer.ts): rtkQueryEdges bridges each generated-hook
node to its same-file endpoint by the naming convention (strip use + optional
Lazy + Query|Mutation, lowercase head). Component→hook is normal import/call
resolution; the hook→endpoint hop surfaces in explore as `dynamic: rtk query`.
Validated 100% precision (hooks == synth edges, 0 cross-file) on basetool (54),
minusx-metabase (11), shapeshift (13); 0 on the uwave-web control (no createApi
→ a complete no-op). The sentinel gate correctly ignores hand-written
look-alikes (shapeshift's useFoxyQuery is a real custom hook, never bridged).
Full suite green (1608); new __tests__/rtk-query-synthesizer.test.ts.
