Make help easier to find and cloned workspaces open reliably (#2045)

* feat(app): add sidebar help and support menu

Give users a single place to run diagnostics, find shortcuts, and reach the support channels. Share one global diagnostic sheet between Settings and the sidebar so both entry points collect the same report.

* fix(app): keep cloned workspace navigation atomic

A newly merged clone flow still used the previous navigation signature and opened its draft tab separately. Route the cloned workspace and its draft target through the unified navigation command so attention selection cannot replace the intended tab.

* test(app): harden sidebar help coverage

Accept both the Discord invite URL and its canonical redirect, assert placement through real element geometry, and remove an unnecessary diagnostic-host callback.

* test(app): cover support redirect variants

Keep the help-menu E2E stable across prerelease versions and the valid redirect forms returned by Discord and GitHub.
