Add tools.cron.command_allowed_remotes so remote channels can be
explicitly allowlisted for command-executing cron jobs. Entries support
channel names, channel:chat_id pairs, and a literal * to allow every
non-empty channel while preserving the default deny posture.
The existing allow_command and command_confirm checks still apply after the
channel gate. Update tests, config examples, and cron documentation for the
new option.
* Support streaming
* fix: stream pico reasoning updates
Route Pico reasoning through the active streamer and hide empty thought placeholders.
* fix: harden configured streaming delivery
* fix ci
* fix split issue
Change incorrect object format model.primary/fallbacks to correct
flat format model_name/model_fallbacks in Agent defaults example.
The AgentDefaults struct does not support the object format used
in AgentConfig, so the documentation example was misleading.
