_getCharacterList() had two bugs that silently dropped every
user-created persona from the group participant picker:
1. The /api/presets/templates endpoint returns a JSON array directly,
but the code read `data.templates` (always undefined). The forEach
over `data.templates || []` iterated over an empty array every time,
so no user templates were ever added.
2. Even if the array had been read correctly, the `t.isCharacter` guard
would have filtered them all out — user templates are saved by
presets.js without that flag, which is only present on built-in
PROMPT_TEMPLATES entries.
Fix: accept both the direct-array and the {templates:[]} shapes, drop
the isCharacter guard (user_templates are personas by definition), and
use the correct field name (system_prompt, not prompt) so the character
prompt actually reaches the group chat.

Two related bugs in the Cookbook task lifecycle:
1. "Stop all" fired kills via .click() inside a synchronous forEach but
showed the success toast immediately after — the toast appeared before
any of the async kill requests had been sent, giving the user false
confidence the tasks were stopped.
2. The download auto-retry logic (triggered when DOWNLOAD_FAILED appears
in the task output) had no way to distinguish a network interruption
from a deliberate user stop. A download stopped via "Stop all" or the
individual Stop button could be silently restarted up to two times by
the background monitor.
Fix: persist _userStopped: true to localStorage at the moment the user
clicks Stop (individually) or Stop all. The auto-retry guard checks this
flag before relaunching the download. The flag is written BEFORE the
kill requests fire so there is no window where the monitor can race.
Fixes#1458
