Function scan_drupal_directories

src/classmap_scanner.rs:757–809

Scan Drupal-specific directories for PHP symbols, bypassing `.gitignore`. Drupal projects typically exclude their web root directories (`web/core`, `web/modules/contrib`, etc.) from version control via `.gitignore` because those files are managed by Composer. The normal gitignore-aware walkers would therefore silently skip the most important parts of the codebase. This function walks with gitig

/// indexing duplicate class definitions from unit-test fixtures.
