//! Resolved settings and RepoPrompt override policy for parallel runs.
//!
//! Responsibilities:
//! - Build `ParallelSettings` from resolved config and CLI options.
//! - Apply agent override rules specific to parallel worker processes.
//!
//! Not handled here:
//! - Workspace-root gitignore validation (see `preflight.rs`).
//! - Orchestration or worker lifecycle.
//!
//! Invariants/assumptions:
//! - `Resolved` reflects the active repo and merged config.
//! - Parallel workers must not inherit RepoPrompt plan/tooling modes that assume a single workspace.
