update_task lets the agent adjust prompt/recurrence/processAfter/script
on a live scheduled task without losing the series id the user already
knows. Empty string clears recurrence/script.
list_tasks now groups by series_id so recurring tasks show as one row
(the live pending/paused occurrence) instead of one per firing — the
id displayed is the stable series handle that update/cancel/pause/resume
all match against.

Recurring tasks spawn a new messages_in row per occurrence. Cancel
only matched the completed row the agent remembered, leaving the
live next occurrence running. Tag every row in a recurrence chain
with the originating task's id (series_id) so cancel/pause/resume
can reach any live row in the series. Cancel also clears recurrence
to prevent the sweep from cloning a cancelled task. Kind-aware id
prefix on recurrences (task- instead of msg-) keeps list_tasks output
consistent across occurrences.
