The root and Rust-facing docs now point readers at a single task-oriented usage guide with build, auth, CLI, session, and parity-harness examples. This also fixes stale workspace references and updates the Rust workspace inventory to match the current crate set.
Constraint: Existing README copy still referenced the old dev/rust status and needed to stay lightweight
Rejected: Fold all usage details into README.md only | too much noise for the landing page
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep USAGE examples aligned with when CLI flags change
Tested: cargo build --workspace; cargo test --workspace
Not-tested: External links and rendered Markdown in GitHub UI
