Colby McHenry 64426cad93 fix(react): recognize forwardRef/memo/styled components + index JSX-file routes (#841) ...

forwardRef/memo/styled-wrapped component consts were classified as plain
`constant` nodes (the initializer is a call/tagged-template, not a bare arrow),
so the JSX-render synthesizer and component resolution skipped them — callers
and impact returned empty for the entire shadcn/ui-style UI layer. Recognize
them in the tree-sitter extractor as `component` nodes (correct body range +
callee capture), PascalCase-gated so a memoization util stays a constant.

Separately, the `react` resolver's `languages` lacked 'tsx'/'jsx', so its
`extract()` never ran on JSX files — React Router `<Route>`/createBrowserRouter
and Next.js page routes (which only live in .tsx/.jsx) were never indexed. Add
'tsx'/'jsx' and make `extract()` route-only: the component/hook regex it carried
duplicated tree-sitter nodes (a `useAuth` became two `function` nodes) and is
fully superseded by the extractor now.

Validated before/after: taxonomy 0->99 component nodes (35 w/ callers) + 1->15
routes; radix 0->262 components (80 w/ callers); cypress-realworld-app 45->52
routes (7 <Route> tags from .tsx); non-React control unchanged; node count
stable. New tests: react-hoc-component.test.ts + a route e2e in
frameworks-integration.test.ts.

Root-caused by @maxmilian (#846); reported by @Arlandaren.
