Subject: [PATCH] feat(agents): inject environment context into OmO system
 prompt
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add user time and system context to OmO agent prompt to help the model
understand the temporal context of the conversation.

Injected context includes:
- Working directory
- Platform (darwin/linux/win32)
- Current date and time
- Timezone
- Locale

Closes #51
