feat(cron): add agentId filtering to cron list (#77602)

Summary:
- This PR adds optional `agentId` filtering to `cron.list`, auto-fills it for agent tool calls, exposes `openclaw cron list --agent`, updates generated protocol clients, docs, changelog, tests, and prompt fixtures.
- Reproducibility: yes. The motivating behavior is source-reproducible on current main because cron tool, CLI, ... e list paths do not accept or apply `agentId`; the PR diff adds that path with focused regression coverage.

Automerge notes:
- Ran the ClawSweeper repair loop before final review.
- Included post-review commit in the final squash: chore: regenerate protocol schema after adding agentId to CronListParams
- Included post-review commit in the final squash: feat(cron): add agentId filtering to cron list

Validation:
- ClawSweeper review passed for head 35b692bc97.
- Required merge gates passed before the squash merge.

Prepared head SHA: 35b692bc97
