Feat/add skill tool (#11051)

* feat: add SkillTool component and integrate into agent tools

- Introduced SkillTool component for rendering skill-related functionality.
- Updated MessageAgentTools to include SkillTool in the tool renderers.
- Enhanced MessageTool to recognize 'Skill' as a valid agent tool type.
- Modified handleUserMessage to conditionally handle text blocks based on skill inclusion.
- Added SkillToolInput and SkillToolOutput types for better type safety.

* feat: implement command tag filtering in message handling

- Added filterCommandTags function to remove command-* tags from text content, ensuring internal command messages do not appear in the user-facing UI.
- Updated handleUserMessage to utilize the new filtering logic, enhancing the handling of text blocks and improving user experience by preventing unwanted command messages from being displayed.

* refactor: rename tool prefix constants for clarity

- Updated variable names for tool prefixes in MessageTool and SkillTool components to enhance code readability.
- Changed `prefix` to `builtinToolsPrefix` and `agentPrefix` to `agentMcpToolsPrefix` for better understanding of their purpose.
