Add document comments to Activity classes

[Copilot]

This PR adds XML documentation comments to all Activity classes in the project that were previously missing them.

Changes

Added proper XML documentation comments to the following classes:

• GetClimateActivity
• GetHotelActivity
• SynthesizerWithAdditionalInfoActivity
• SynthesizerActivity
• GetDestinationSuggestActivity
• GetSightseeingSpotActivity
• SubmitReservationActivity
• AgentDeciderActivity
• AgentOrchestrator

These documentation comments provide:

• Clear descriptions of each class's purpose
• Their role in the multi-agent system
• Their primary responsibilities

Example:

/// <summary>
/// Activity class responsible for retrieving climate information for a specified location.
/// Part of the multi-agent travel concierge system.
/// </summary>
public class GetClimateActivity

The comments follow the style already established in the project (like in AgentActivityName.cs) and will make the codebase more maintainable and easier to understand for new developers.

Fixes #50.

Warning

Firewall rules blocked me from connecting to one or more addresses

I tried to connect to the following addresses, but was blocked by firewall rules:

• cdn.fwupd.org
  • Triggering command: /usr/bin/fwupdmgr refresh (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to my firewall allow list
