Subject: [PATCH] fix(model_metadata): add gemma-4 and gemma4 context length
 entries

Fixes #12976

The generic "gemma": 8192 fallback was incorrectly matching gemma4:31b-cloud
before the more specific Gemma 4 entries could match, causing Hermes to assign
only 8K context instead of 262K. Added "gemma-4" and "gemma4" entries before
the fallback to correctly handle Gemma 4 model naming conventions.
