refactor: Replace _impl aliases with explicit wrapper functions in R/structural-properties.R

[Copilot]

Replaced direct _impl function aliases with explicit wrapper functions that forward arguments individually.

Changes

Converted 13 functions from direct aliases to explicit wrappers:

• k_shortest_paths, reciprocity, edge_density
• feedback_arc_set, feedback_vertex_set
• which_multiple, any_multiple, count_multiple
• which_loop, any_loop
• is_connected, which_mutual, knn

Pattern

Before:

edge_density <- density_impl

After:

edge_density <- function(graph, loops = FALSE) {
  density_impl(
    graph = graph,
    loops = loops
  )
}

Each wrapper explicitly forwards all parameters using arg = arg notation, preserving default values and ... where applicable.

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

Functions to update:

• k_shortest_paths <- get_k_shortest_paths_impl
• reciprocity <- reciprocity_impl
• edge_density <- density_impl
• feedback_arc_set <- feedback_arc_set_impl
• feedback_vertex_set <- feedback_vertex_set_impl
• which_multiple <- is_multiple_impl
• any_multiple <- has_multiple_impl
• count_multiple <- count_multiple_impl
• which_loop <- is_loop_impl
• any_loop <- has_loop_impl
• is_connected <- is_connected_impl
• which_mutual <- is_mutual_impl
• knn <- avg_nearest_neighbor_degree_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,
    ...
  )
}
