//! String normalization helpers for search and filtering.
//!
//! Responsibilities:
//! - Normalize strings for consistent comparison (trim + lowercase)
//!
//! Not handled here:
//! - Regex compilation or pattern matching
//! - Fuzzy matching normalization (handled by nucleo_matcher)
//!
//! Invariants/assumptions:
//! - All normalized strings are lowercase and trimmed
//! - Empty strings after trimming are filtered out by callers

/// Normalize a string for comparison by trimming and lowercasing.
///
/// Used for both scope and tag normalization since they share
/// the same semantics (case-insensitive matching after trim).
pub fn normalize(value: &str) -> String {
    value.trim().to_lowercase()
}
