/// Two scenarios that previously behaved unexpectedly:
/// 1. `rumdl check --config ./project/.rumdl.toml project` did not find the config file
///    when the path was relative to cwd (expected shell autocomplete behavior)
/// 2. Exclude patterns were resolved relative to cwd instead of project root,
///    causing excludes to fail when running from outside the project directory

// =============================================================================
// DIRECTORY-ONLY EXCLUDE PATTERN TESTS
// =============================================================================
// These tests verify that exclude patterns WITHOUT glob suffixes (e.g., "content/blog/2014")
// correctly exclude all files within those directories. This was the key issue from
// HarHarLinks' comment on issue #185 - patterns like "content/blog/2014" were not
// matching "content/blog/2014/file.md" because globset only matches exact paths.
//
// The fix: expand directory-only patterns to include "/**" suffix.

/// Create a project structure that mimics HarHarLinks' scenario from issue #185:
/// ```
/// parent/
///   project/
///     .rumdl.toml (with exclude = ["content/blog/2014"])
///     content/
///       blog/
///         2014/
///           old-post.md (should be excluded)
///           archived/
///             deep.md (should also be excluded - nested)
///         2015/
///           new-post.md (should be linted)
///       pages/
///         about.md (should be linted)
