The active Rust CLI path now keeps users informed during streaming with a waiting spinner,
inline tool call summaries, response token usage, semantic color cues, and an opt-out
switch. The work stays inside the active + renderer path and updates
stale runtime tests that referenced removed permission enums.
Constraint: Must keep changes in the active CLI path rather than refactoring unused app shell
Constraint: Must pass cargo fmt, clippy, and full cargo test without adding dependencies
Rejected: Route the work through | inactive path would expand risk and scope
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep future streaming UX changes wired through renderer color settings so remains end-to-end
Tested: cargo fmt --all; cargo clippy --all-targets --all-features -- -D warnings; cargo test
Not-tested: Interactive manual terminal run against live Anthropic streaming output
