fix: Update Terraform MCP server tool permissions (#232)

- Fix tool name mismatch with HashiCorp terraform-mcp-server
- Use correct tool names: mcp__terraform__search_providers, etc.
- Previous run showed MCP connectivity working but permission errors
- Both terraform and context7 servers now connect successfully

Resolves: #224
