/// Package parser trait for extracting metadata from package manifest files.
///
/// Each parser implementation handles a specific package manager/ecosystem
/// (npm, Maven, Python, Cargo, etc.) and extracts standardized metadata into
/// `PackageData` structures compatible with ScanCode Toolkit JSON output format.
///
/// # Implementation Guide
///
/// Implementors must provide:
/// - `PACKAGE_TYPE`: Package URL (purl) type identifier (e.g., "npm", "pypi", "maven")
/// - `is_match()`: Returns true if the given file path matches this parser's expected format
/// - `extract_packages()`: Parses the file and returns all extracted package metadata
///
/// # Error Handling
///
/// Parsers should handle errors gracefully by returning default/empty `PackageData`
/// and logging warnings with [`crate::parser_warn!`] rather than panicking. Scanner
/// dispatch captures those warnings and attaches them to `FileInfo.scan_diagnostics` so
/// CI output and serialized scan results stay aligned.
/// This allows the scan to continue processing other files even when individual
/// files fail to parse.
///
/// # Example
///
/// ```no_run
/// use provenant::models::{PackageData, PackageType};
/// use provenant::parsers::PackageParser;
/// use std::path::Path;
///
/// pub struct MyParser;
///
/// impl PackageParser for MyParser {
///     const PACKAGE_TYPE: PackageType = PackageType::Npm;
///
///     fn is_match(path: &Path) -> bool {
///         path.file_name().is_some_and(|name| name == "package.json")
///     }
///
///     fn extract_packages(path: &Path) -> Vec<PackageData> {
///         vec![PackageData::default()]
///     }
/// }
/// ```
