Pull Request Overview

This PR introduces a new linter rule for detecting network-related functions in R code. The implementation refactors existing code to create reusable utilities for function detection patterns.

• Adds a new "network-functions" linter rule to flag functions that perform network operations
• Extracts common function-finding logic into a reusable utility module
• Updates the deprecated functions rule to use the new shared utility
