Navie hangs after context search completes

Navie responses sometimes appear to hang indefinitely until a timeout occurs, ultimately displaying the error message:

No search request with id: <uuid>

Subsequent prompts (such as next steps) do appear to resolve correctly.

Environment:

Operating System: Windows 11
IDE: JetBrains
AppMap Plugin for JetBrains: v0.77.0
AppMap CLI: v3.185.2
OpenAI Model: GPT-4o (August)
Network: Corporate proxy configured

Steps to Reproduce:

1. Pin a text file in the IDE.
2. Issue the prompt: @plan.
3. Observe the context:
   • The pinned file is successfully included.
   • Sequence diagrams and code snippets appear, indicating that indexing, vector terms, context search, etc. are working.
4. Notice the behavior:
   • The text cursor blinks for several minutes until the request times out.
   • Navie then displays the error: No search request with id: <uuid>.
5. Follow-up:
   • Subsequent prompts resolve normally.

Expected Behavior:
Navie should return the results for the context search promptly without hanging or timing out.

Actual Behavior:
After the context search completes, Navie hangs (as indicated by a blinking cursor) until it times out, ultimately presenting an error message regarding a missing search request ID.

No files, tests, or entry points are named. Reproduce @plan in JetBrains with a pinned text file, then trace the context-search request lifecycle through the TypeScript client; done means the response returns without hanging, timing out, or showing a missing search request ID.
