/**
 * Shrinks the context of the given messages to fit within model limits.
 * Uses a smart trimming algorithm:
 * 1. Truncates the middle of large messages (preserving start and end).
 * 2. Removes oldest conversation pairs (user/assistant) if needed.
 * 3. Never touches the 'system' message or the very last user message.
 * 
 * Returns R_SUCCESS if shrinkage was performed, or error if not possible.
