Function parse_pattern_base_path 

pub fn parse_pattern_base_path(pattern: &str) -> (PathBuf, String)

Parses a pattern string to extract the base path and pattern components.

Handles three cases:

1. Patterns with path separators and absolute/relative parents
2. Patterns with path separators but simple relative paths
3. Simple patterns without path separators

Arguments

• pattern - The glob pattern string (e.g., “agents/.md”, “../foo/.md”)

Returns

A tuple of (base_path, pattern_str) where:

• base_path is the directory to search in
• pattern_str is the glob pattern to match files against

Examples

use std::path::{Path, PathBuf};
use agpm_cli::resolver::path_resolver::parse_pattern_base_path;

let (base, pattern) = parse_pattern_base_path("agents/*.md");
assert_eq!(base, PathBuf::from("."));
assert_eq!(pattern, "agents/*.md");

let (base, pattern) = parse_pattern_base_path("../foo/bar/*.md");
assert_eq!(base, PathBuf::from("../foo/bar"));
assert_eq!(pattern, "*.md");
