feat(v2): add pre-task script hook for scheduled tasks

Browse Source 
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.
