internal/upstream/core/connection.go: File content (34031 tokens) exceeds maximum allowed tokens (25000)

I noticed this in claude:

```
⏺ Read(internal/upstream/core/connection.go)
  ⎿  Error: File content (34031 tokens) exceeds maximum allowed tokens (25000). Please use offset and limit parameters to read specific portions of the file, or use the GrepTool to search for specific content.

```

Might be a sign this needs some cleanup/refactoring 😅
