Bug Description

Hermes reconnects after 180 seconds of no response from the provider, even though oMLX is still actively processing the request.

Steps to Reproduce

1. Run Hermes on latest release
2. Use oMLX 0.3.5 as a local provider
3. Use Qwen3.5-122B-A10B-8bit as main model
4. Run a long-context session with substantial accumulated history
5. Wait for a slow request / long prefill phase
6. Hermes emits:
   • No response from provider for 180s ... Reconnecting...
7. oMLX continues working and does not appear dead

Expected Behavior

Hermes should not reconnect or abandon the provider request if the provider is still actively processing a long-running request.

Ideally one of these should happen:

1. The provider watchdog should be configurable
2. Hermes should distinguish between “provider silent but still processing” vs “provider actually dead”
3. Long local-provider workloads should be allowed to run longer without forced reconnects

Actual Behavior

Hermes reconnects after 180s of no response, even though oMLX is still processing normally.

This causes:

• abandoned long-running requests
• repeated reconnect / retry behavior
• sessions failing before reaching compression
• instability in long-context workflows
