Extends the Razor/Blazor markup parser to analyze the C# inside `@code { }`,
`@functions { }`, and `@{ }` blocks — the Blazor analog of Svelte's <script>
delegation. Blocks are brace-matched (skipping strings/comments), wrapped in a
synthetic class so tree-sitter parses the component's fields/methods in a class
context, then their external references (service/DTO calls, `new X()`, type uses)
are attributed to the component. No per-member nodes are added — coverage only
needs the dependency edges to external types, so node count stays flat.
So a service/DTO used only in component logic (`@code { _svc.Load(); }`) is now
linked. Validated: eShopOnWeb 79.9% -> 81.2%; the test proves a `@code`
`new CatalogService()` covers CatalogService. Full suite 1176; 1 regression test;
no node explosion (entry-excluded count unchanged).
Residual ASP.NET gap is now the DTO name-collision (`CatalogBrand` exists as both
a domain entity and a DTO — the markup/@code ref resolves to the entity) — the
next increment is `@using` namespace disambiguation, tracked in the scope doc.
