Add worker run inspection and cooperative CLI controls

[highbyte]

Wrighty skills can now inspect and cooperatively stop an exact worker run through workers show, workers drain, and workers interrupt. CLI and web-hosted runs reuse the existing registry and worker-control protocol, including process-start identity verification and independent control of runs sharing a web-host PID. Stop responses distinguish an accepted request from completed shutdown.

Foreground workers emit structured startup and completion receipts with run identity, selection, limits, ownership, and status/log locations. Worker-spawned sessions carry a recursion marker that prevents launching another worker. The bundled skill and documentation explain pickup assessment, launch authorization, foreground/terminal lifetime, and ambiguous outcomes. This adds no service installation, detached worker manager, or automatic restart.

Validation:

• 2,470 .NET tests, 96 JavaScript tests, eight packaging/smoke-script tests, and skill validation pass.
• Executable smoke checks cover inspection, drain, interrupt, idle timeout, recursive-launch refusal, and targeted fake-agent process-tree interruption with item finalization; no paid vendor calls.
• Local SonarAnalyzer rebuild has no findings on changed code. Hosted merge gates will validate the pushed commit.
