refactor: Replace _impl aliases with explicit wrappers in R/embedding.R

[Copilot]

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

Changes

• embed_adjacency_matrix: Replaced alias with wrapper forwarding 7 parameters (graph, no, weights, which, scaled, cvec, options)
• dim_select: Replaced alias with wrapper forwarding single parameter (sv)
• embed_laplacian_matrix: Replaced alias with wrapper forwarding 7 parameters (graph, no, weights, which, type, scaled, options)

Example

Before:

embed_adjacency_matrix <- adjacency_spectral_embedding_impl

After:

embed_adjacency_matrix <- function(graph, no, weights = NULL, which = c("lm", "la", "sa"), scaled = TRUE, cvec = strength(graph, weights = weights) / (vcount(graph) - 1), options = arpack_defaults()) {
  adjacency_spectral_embedding_impl(
    graph = graph,
    no = no,
    weights = weights,
    which = which,
    scaled = scaled,
    cvec = cvec,
    options = options
  )
}

All wrappers use explicit arg = arg notation. Function signatures match their corresponding _impl functions exactly.

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

Functions to update:

• embed_adjacency_matrix <- adjacency_spectral_embedding_impl
• dim_select <- dim_select_impl
• embed_laplacian_matrix <- laplacian_spectral_embedding_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,
    ...
  )
}
