Module walk 

Shared bounded directory walkers.

Replaces the per-plugin collect_*_files helpers that previously lived in nearly every module. Each function performs an iterative (no-recursion) walk with optional bounds and returns a sorted Vec<PathBuf> for deterministic test output.

Variants

• walk_files — single-extension filter, no bounds.
• walk_files_multi — multiple extensions (case-insensitive).
• walk_files_bounded_depth — single extension with a maximum directory depth (for content trees).
• walk_files_bounded_count — single extension with a maximum file-count cap (for live-reload / batch I/O fast-paths).

All variants return Ok(Vec::new()) when the root directory does not exist or is not a directory — matching the convention used by every previous local collector in the crate.

Symlinks

The collecting walkers follow symlinked directories, but enter each real directory (by canonical path) at most once. A link back to an ancestor is therefore skipped instead of walked again, so a symlink loop can neither repeat files nor make the walk branch without end. Subdirectories are visited in sorted order, so when one directory is reachable by two names the name kept is the same on every platform.

Functions

visit_files_bounded_depth

Visits every file with extension ext under dir, in a deterministic order, without materialising the file list.

walk_files

Recursively collects files matching extension under dir.

walk_files_bounded_count

Recursively collects files matching extension, capped at max_files. Provides with_context on the underlying read_dir failure.

walk_files_bounded_depth

Recursively collects files matching extension, bounded by depth.

walk_files_multi

Recursively collects files matching any of extensions under dir.
