Claude cad2569360 Add mcp-context-warning plugin to warn about high MCP context usage
This plugin warns users when their MCP servers are consuming significant
context (>20k tokens). Many users don't realize MCP servers take up context
space, which can lead to unexpectedly fast context exhaustion.

The plugin:
- Runs a SessionStart hook to check MCP configurations
- Estimates token usage based on server and tool counts
- Shows a warning with server breakdown if estimated usage > 20k tokens
- Provides guidance on how to disable unused MCP servers
