The fetchCompatibleModelIds() function had no timeout on its fetch() call,
causing /v1/models to hang indefinitely when an openai-compatible provider
was unreachable or slow to respond.
Additionally, upstream/cross-instance connections (provider IDs containing
a UUID suffix like openai-compatible-chat-XXXXXXXX) would trigger recursive
/models fetches between instances, creating infinite loops.
Fixes:
- Add AbortController with 5-second timeout to the fetch() call
- Skip dynamic model fetching for upstream/cross-instance connections
(detected by UUID suffix pattern in provider ID)
- Existing try/catch already handles abort errors gracefully
