Make pet more conversational with engaging dialogue

[Copilot]

Pet responses were limited to sounds and 1-2 short sentences. Updated LLM integration to encourage full conversational dialogue.

Changes

• System prompt: Replaced "Keep responses to 1-2 short sentences max" with instructions to have real conversations, share feelings, ask questions, and tell stories
• Token limit: Increased NumPredict from 100 → 250 to allow longer responses
• User prompt: Changed from "Respond as the pet (1-2 sentences)" to "Respond as the pet and have a conversation with your owner"
• Fallback messages: Expanded all state-based and action-based messages to be conversational with full sentences and questions
• MockClient: Updated canned messages for no-LLM mode; made consistent with fallback messages

Example

Before:

*yawns* So sleepy...

After:

*yawns widely* I'm feeling so sleepy... It's been such a busy day! Maybe we could rest together for a bit? That would be really nice... 😴

Original prompt

ok lets make so its more conversetional the pet and does converatstion with the user not just sounds and small sentences
