2.0.6

Show private code connectors in Settings on launch

Private connectors (e.g. the nesher breach-search connector) only became visible
in Settings → Modules after the first chat turn, because the connector rows are
derived from the loaded tool list and the tool server was built lazily on that
first turn. Warm the tool list once at startup and nudge the renderer to
re-fetch, so connectors show immediately. The connector's tools already worked
on first use; this only fixes their visibility.

Bump to 2.0.6.
