Version bump to 0.5.8 and its CHANGELOG entry. Since v0.5.7:

• Spec 028: the suggestion warm-up waits for the chat to be used and for a quiet window, retries a failed phrasing after a window, phrases each miss in its own language, and keeps follow-ups out of the table (Suggestion warm-up after its code review (spec 028) #57).
• A stopped, deleted or timed-out chat turn ends its model call again; the openai-java hold is gone (Cancel the HTTP call when a model stream is closed, drop the openai-java hold #58).
• The frontend builds on Node 26 with Angular 22.2.5 and current dependencies (Build the frontend on Node 26 and update dependencies #53); Gradle 9.9.0 (Update Gradle to v9.9.0 #56).
• On a phone the toasts stack one high (Show only the newest toast on a phone #60); the brand mark at public/logo.png (Add the brand mark as public/logo.png #59); a browser-spec flake fixed (Treat a cancelled transition as ended in the browser specs #54).

No migration, no value to set. After the merge: tag v0.5.8 on the merge commit, then pin it in the chart.
