//! Workspace path resolution helpers.
//!
//! Responsibilities:
//! - Compute the effective workspace root from config and repository location.
//! - Keep tilde expansion and relative-path policy centralized.
//! - Provide the default workspace-root convention for parallel runs.
//!
//! Not handled here:
//! - Workspace creation, cleanup, or git subprocess execution.
//! - Validation of workspace contents.
//!
//! Invariants/assumptions:
//! - Relative workspace roots are resolved against `repo_root`.
//! - The default workspace root stays outside the repository working tree.
