📚 Description

Added additional tools to MCP, so it can retrieve only sections for components, like, theme, or slots.

• list_component_sections - lists available sections for a component
• get_component_sections - fetches only specified sections
• Enhanced get_component with optional sections parameter

I'm in a middle of a large migration and tried to connect MCP server to help me out with it, but it fetches whole docs for components, when it actually needs to learn the new slot names, or how themes structure has changed for specific components. For example, fetching table docs alone throws warnings about token count.

Claude says it could save him 70-90% of tokens. :sweat_smile:

@BerzinsU I totally agree that some components are extremely long and probably overload the context of some models. However, I don't think the solution is to add more tools, but rather to modify and improve the existing ones. I'll try to investigate this!
