Feature Request: Lazy loading for MCP servers and Tools

[liberateyourtech]

Problem

On startup Newelle loads MCP servers, tools etc into the next window on load which very quickly slows down the response times and massively increases token usage
Despite being able to selectivley turn off specific tools for each MCP server (which is great) if you have serveral MCP servers / agents it very quickly becomes unmanageable

Proposed solution

Implement lazy loading for MCP servers and tools, loading them only when needed based on conversation context, potentially based on this implementation, which was integrated into Claude Code only 5 days ago

anthropics/claude-code#7336

Benefits

95% Token Reduction
Longer Conversations
Better Performance: Faster startup, lower memory usage
Scalability: Can add more tools without context penalty

Related improvements

Can we add 'per profile' Tools settings please? e.g

Profile 1: MCP servers A, B
Profile 2: MCP servers C, D

Thank you once again for Newelle, great work!

This should already be implemented

For the rest, I was already thinking how to implement this for a while. I will likely do it for 1.3.5 or 1.4.0
