Streaming fixes for tool calls and duplicate keys

Three fixes land in Open WebUI: streaming no longer breaks on duplicate output keys or tool-call thinking, and user text resembling skill mentions is no longer deleted.

Open WebUI shipped fixes for three streaming and parsing bugs that broke real chat flows. One [1] stopped the chat from silently deleting user text that looks like a skill mention: any `<$...>` run was treated as an inline skill mention and removed before the request reached the model, so snippets like `<$(=MonthStart($(vMaxMonthEndINC)))` disappeared mid-message. The mention regexes accepted any character except `|` and `>` as the skill id; they now match only validated skill ids.

Streaming with reasoning-capable models froze mid-stream [2] when a stream event addressed an output slot past the end of the array; missing slots were filled with the event's value, causing a Svelte each_key_duplicate error. The chat now shows the first chunk and continues instead of waiting for generation to finish. Separately, post-tool-call thinking was streamed into the main chat area and only jumped to the collapsed Thoughts section once the turn finished [3]. Each tool round appended an empty placeholder that the browser held onto, misaligning subsequent output indices; thinking now streams into Thoughts immediately.

Meanwhile, translations continue: German (de-DE) [4] and Catalan [5] were updated with new strings and typo fixes. No user-facing config or version changes accompany these patches.

A primary-source description of the skill mention bug says: "the mention regexes accepted any character except `|` and `>` as the skill id" [1].
