feat(work-status): add opt-in turn statistics (#3177)

Add optional completed-turn statistics without changing the existing panel layout. Separate final text delivery speed from whole-turn throughput, preserve scope and opt-in settings, and explain each metric with localized delayed tooltips.

Validated focused telemetry, lifecycle, sync and persistence tests, all-workspace type-check and lint, web builds, the 12-locale narrow layout, and full GitHub CI.
