Bump SharpConsoleUI to 2.5.0 and drop redundant nav invalidation

[nickprotop]

Changed

• Update SharpConsoleUI to 2.5.0.

Fixed

• Remove a redundant explicit navigation invalidation in the workbench. NavigationItem.Subtitle now self-invalidates via its setter in SharpConsoleUI 2.5.0, so badge subtitle updates refresh without the extra call.

Closing this PR.

Bumping SharpConsoleUI to 2.5.0 manually here was a mistake on my part — apologies. The repo's daily package-update workflow already bumps NuGet versions on main automatically, so the version bump didn't need to be done by hand in a PR.

While investigating, this also revealed a side effect: changing Directory.Packages.props forces a full rebuild, which makes the Release build re-run analyzers across the whole project. That surfaced 19 pre-existing MA0206 ("remove unnecessary braces in type declaration") errors in Source/Cli/Registration/*.cs — files this PR never touched. Because the auto-update workflow builds in Debug (warnings only), these had been sitting latent on main without failing any build; the Release PR gate is the first thing to turn them into errors.
