Release exp: no false no-response after final tool (#5990, closes #5686). Thanks @jtstothard.

Final-answer detection understands structured content parts (text after tool-use
boundaries); genuine empty completions still show no_response; terminal provider
error still surfaces as apperror (never masked). Codex SAFE round2 (3 precedence
findings fixed), stream-gate GREEN all modes. Maintainer: updated the #5940 source-
assert test for the _captured_terminal_failure rename.

 ### Fixed
 
+- **No more false "No response from provider" after a completed answer that used tools.** When an assistant turn ended with a real final answer delivered as structured content following tool calls (common with reasoning models and multi-tool turns), the completion detector could miss the final text and render a spurious "No response from provider" card under the finished reply. Final-answer detection now understands structured content parts (text after tool-use boundaries), while genuine empty completions still correctly show the no-response notice, and a real terminal provider error still surfaces as an error (never masked as a final answer). Thanks @jtstothard. (#5990, #5686)
+
 - **Cron unread ("Tasks") dots are now scoped to the active profile — no more ghost dots after switching.** In multi-profile setups, the session-sidebar unread dot and the Tasks badge could keep showing a cron completion from a *different* profile after you switched, and the count could resurrect from a stale poll. Cron completion markers now carry their source + owning profile, are cleared for the profile you switch away from (including legacy/untagged markers), and a previous-profile poll response can no longer restore a stale unread. Non-cron completion unread and the current profile's own cron unread are preserved; default ↔ renamed-root aliases are treated as the same profile so a root cron marker is neither wrongly cleared nor wrongly kept. Thanks @jbbottoms. (#5975, #5960)
 
 - **The Docker "manual update" banner instruction is now localized.** On Docker/no-git deployments the update banner shows the manual update command; that guidance string was hardcoded in English. It now goes through the i18n system, so it renders in the active language (English fallback where a translation isn't present yet). Thanks @jbbottoms. (#5973, #5959)
