feat(chat-run-socket): record usage from Hermes session in syncFromHermes

Call updateUsage() in syncFromHermes to record token usage data from Hermes
ephemeral session to local DB. This ensures accurate usage tracking including:
- input_tokens
- output_tokens
- cache_read_tokens
- cache_write_tokens
- reasoning_tokens
- model

The usage data comes from the Hermes session detail which contains
accurate token counts from the upstream LLM provider.
