Analyzer::Rust::Salvo

Salvo analyzer (tree-sitter port). Salvo wires routes in two shapes, both handled here:

1. Router-chain DSL: Router::with_path("users/<id>").get(get_user) Router::new().path("users").hoop(auth).get(list).post(create) Each .<verb>(handler) is paired with the nearest enclosing .with_path(...) / .path(...) found by walking up its receiver chain — so middleware (.hoop(...)) and verb chaining (.get(a).post(b)) between the path and the verb don't break detection.

2. Attribute macro: #[endpoint(method = Post, path = "/api/submit/<id>")] async fn submit_form(...) { ... }

Router chains are frequently assembled inside a vec![ ... ] macro (impl Routers { fn build() -> Vec<Router> { vec![Router::new()…] } }). tree-sitter leaves a macro body as a flat token_tree with no call_expression nodes, so those routes are invisible to a plain AST walk. We recover them by re-parsing each router-bearing macro body as an expression fragment and mapping line numbers back.
