//! Utilities Module - shared infrastructure (v0.1)
//!
//! Contains helper functions and data structures used across the codebase:
//! - `constants`: Centralized timeouts and limits
//! - `fs`: Atomic file write operations
//! - `interner`: String interning for recurring task IDs (`Arc<str>` deduplication)
//! - `jsonpath`: Minimal JSONPath parser for path resolution
