ralph-agent-loop 0.4.0

//! Gitignored allowlist sync tests for parallel workspace state synchronization.
//!
//! Responsibilities:
//! - Verify `.env*` allowlist sync behavior for ignored repo files.
//! - Verify ignored directories and worker-parent paths are excluded.
//! - Verify unit-level filtering behavior for gitignored path normalization.
//!
//! Does NOT handle:
//! - `.ralph` runtime-tree recursion coverage.
//! - Custom bookkeeping path mapping scenarios.
//!
//! Invariants:
//! - Test names and assertions match the prior flat suite exactly.
//! - Filtering expectations remain narrow by design (`.env*` only).
