Wait for an intentional sidecar dispose to exit before refreshing capabilities, and ignore exit events from stale sidecar processes. This prevents a refresh from killing the old process and then having that old exit reject the new capabilities request with an unexpected sidecar exit error.

Force-refreshing sidecar capabilities now disposes the idle sidecar process before re-querying capabilities, so Kopaya can pick up backend sidecar changes and refreshed Copilot connection state without a full app restart.
Add a small helper and regression tests for the refresh decision.
