claude_storage 1.5.1

//! Integration tests for the `clg .project.path` command.
//!
//! ## Source
//!
//! - Spec: `tests/docs/cli/command/08_project_path.md`
//!
//! ## Coverage
//!
//! - INT-1: Default (cwd) computes correct storage path
//! - INT-2: `path::` override computes path for given directory
//! - INT-3: `topic::` appended as suffix to encoded path
//! - INT-4: `path::` with `topic::` combines both
//! - INT-5: Output is a single line ending with /
//! - INT-6: Exits with code 0 for nonexistent path
//! - INT-7: ~ prefix expanded in `path::`
//! - INT-8: `path::.` resolves to cwd
//! - INT-9: Empty `topic::` rejected
//! - INT-10: `topic::` with slash rejected
