//! File type recognizers for various package archives and binary formats.
//!
//! This module contains simple file-type recognizers that identify packages by
//! their file extensions or path patterns. These recognizers do NOT parse file
//! contents - they only tag files with the appropriate package_type and datasource_id.
//!
//! # Implementation Notes
//!
//! - All recognizers use the `file_recognizer!` macro to reduce boilerplate
//! - Recognizers return minimal PackageData with only package_type and datasource_id set
//! - These correspond to Python's misc.py NonAssemblableDatafileHandler classes
//! - No actual parsing is performed (Python also has `# TODO: parse me!!!`)
//! - Some recognizers use magic byte detection for disambiguation (Squashfs, NSIS, InstallShield)

/// Helper macro to define file-type recognizers with minimal boilerplate.
///
/// Each recognizer matches specific file patterns and returns a minimal
/// PackageData structure with only package_type and datasource_id populated.
///
/// # Arguments
///
/// * `$name` - Struct name for the recognizer
/// * `$pkg_type` - Package type string (e.g., "jar", "war", "meteor")
/// * `$datasource` - Datasource ID string (e.g., "java_jar", "meteor_package")
/// * `$match_fn` - Closure that takes a &Path and returns bool for matching
