Problem

find_api_callers did not find this C# client call (a real client library):

string url = assistantInstanceId.HasValue
    ? $"api/v2/Assistants/run/instance/{assistantInstanceId.Value}"
    : $"api/v2/Assistants/run/{assistantEntityId}";
using var httpRequest = new HttpRequestMessage(HttpMethod.Post, url) { Content = content };

The C# rule only knew httpClient|_httpClient|client.<Verb>Async("literal"). Also, the fetch rule allowed any text between httpRequest and a later (, so httpRequest.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("text/event-stream")) became a false GET /text/event-stream call.

Fix

• New app/services/chunking/csharp_client_calls.py (used for C# files only):
  • new HttpRequestMessage(HttpMethod.Post, ...) and new HttpRequestMessage(new HttpMethod("PATCH"), ...)
  • <anything>Client.<Verb>*Async(...), with an optional generic type argument
  • URL arguments: a literal, an interpolated string ($"..."), "path/" + id (becomes path/{id}), or a variable. A variable is resolved from its nearest assignment in the 40 lines above; each URL literal in that statement is one call (both branches of a conditional).
• _FETCH_CALL now matches only the call itself (fetch(, requestJson<T>().
• docs/mcp-tools-and-resources.md and REQUIREMENTS.md updated.

Tests

tests/test_csharp_client_calls.py: the conditional URL variable (both routes, matched against api/v{version}/assistants/run/{eid}), interpolated literals with a custom client name and generic arguments, concatenation, variables without a URL are ignored, and other languages are not affected. The existing tests/test_api_client_calls.py passes.
