Scheduled tasks stored process_after as ISO-8601 with `T` and `Z`
(e.g. `2026-04-16T14:37:00Z`) but the due-check queries compared it
via raw `<=` against `datetime('now')`, which returns space-separated
format (`2026-04-16 14:37:00`). Since `'T' (0x54) > ' ' (0x20)`,
every ISO-formatted process_after sorted greater than any SQLite-format
`now`, so tasks were never picked up by either the host sweep's
countDueMessages or the container's getPendingMessages.
Wrapping process_after in datetime() normalises both sides before
comparison. Recurrence rows (written by retryWithBackoff using
datetime('now', ...)) already had SQLite format and were unaffected,
which is why the bug only surfaced for agent-scheduled tasks.

Scheduled tasks can now carry a bash script that runs inside the container
before the agent is invoked. The script prints `{wakeAgent, data?}` on its
last stdout line; if `wakeAgent: false` (or the script errors) the task
row is marked completed and the agent is never queried, saving API calls
on no-op checks. On wake, the script's `data` is injected into the task
prompt. Semantics mirror V1: 30s bash timeout, 1MB buffer, last-line JSON,
error == skip.
Also blocks the Claude SDK's built-in scheduling tools (CronCreate,
CronDelete, CronList, ScheduleWakeup) via `disallowedTools` so tasks
actually flow through `mcp__nanoclaw__schedule_task` and get the script
gate. CLAUDE.md gains a soft pointer explaining why `schedule_task` is
the right path.
