par-term 0.47.0

//! Headless egui tests for clickable status-bar widgets in non-Right sections.
//!
//! The agent-usage and agent-roster widgets used to be clickable only when
//! placed in the Right section (documented as a v1 limitation in
//! docs/features/AGENT_USAGE.md). These tests pin the fix: every section
//! renders widgets through the same click path.
