/// TOOL-FEATURE-001: Package publishing with Ruchy.toml validation
///
/// # Arguments
/// * `registry` - Registry URL to publish to
/// * `version` - Optional version override (reads from Ruchy.toml if None)
/// * `dry_run` - Validate without publishing
/// * `allow_dirty` - Allow publishing with uncommitted changes
/// * `verbose` - Show detailed output
///
/// # Errors
/// Returns error if:
/// - Ruchy.toml not found
/// - Required fields missing (name, version, authors, description, license)
/// - Invalid semver version
/// - Package validation fails
