refactor: Replace _impl aliases with explicit wrapper functions in R/triangles.R

[Copilot]

Replaces direct _impl function aliases with explicit wrapper functions for better code clarity and maintainability.

Changes:

• triangles: Now an explicit wrapper forwarding graph parameter to list_triangles_impl()
• count_triangles: Now an explicit wrapper forwarding graph and vids parameters to count_adjacent_triangles_impl()

Before:

triangles <- list_triangles_impl
count_triangles <- count_adjacent_triangles_impl

After:

triangles <- function(graph) {
  list_triangles_impl(
    graph = graph
  )
}

count_triangles <- function(graph, vids = V(graph)) {
  count_adjacent_triangles_impl(
    graph = graph,
    vids = vids
  )
}

Arguments are forwarded explicitly using arg = arg notation. Function signatures and behavior remain unchanged.

<issue_title>Replace _impl aliases in R/triangles.R</issue_title>
<issue_description>Goal
Review the code in R/triangles.R and replace all direct _impl function aliases with explicit wrapper functions.

Functions to update:

• triangles <- list_triangles_impl
• count_triangles <- count_adjacent_triangles_impl

Instructions

1. Review the code to understand the function signatures
2. Create explicit wrapper functions that forward to the _impl functions
3. Forward each argument individually and explicitly using arg = arg notation
4. Do not use ... unless the _impl function itself uses ...

Pattern
Replace direct aliasing like:

func_name <- func_name_impl

With an explicit wrapper:

func_name <- function(arg1, arg2, ...) {
  func_name_impl(
    arg1 = arg1,
    arg2 = arg2,
    ...
  )
}
